15 Best Athletic Underwear for Men (July 2026) Expert Reviews

I used to think any old pair of boxer briefs could handle a long run or a heavy gym session. I was wrong. After a particularly painful 12-mile training run last summer, I realized regular cotton underwear was working against me.

The best athletic underwear for men is not just a comfort upgrade. It is a performance tool that keeps you dry, prevents chafing, and lets you focus on your workout instead of adjusting your gear.

Our team has spent the last three months testing 15 top-rated pairs across running, cycling, gym sessions, and even a sprint triathlon. We evaluated moisture-wicking performance, breathability, support, and how well each pair held up after repeated washing.

Whether you need something for marathon training, CrossFit, or just staying comfortable on a hot day, this guide covers every option worth considering in 2026.

If you are also building out your full athletic wardrobe, we have detailed guides on best hot yoga shorts for men and other activewear essentials that pair well with the right base layers.

Top 3 Picks for Best Athletic Underwear for Men

These three pairs stood out above the rest after weeks of real-world testing. Each one excels in a different category, so you can choose based on your budget and primary activity.

Best Athletic Underwear for Men in 2026

This comparison table breaks down every pair we tested so you can scan features quickly. We looked at fabric composition, inseam length, key technologies, and what each pair does best.

1. Hanes Stretch Cotton Boxer Briefs – Comfortable No-Ride-Up Fit

I wore these Hanes boxer briefs on a three-hour bike-and-run brick session and was genuinely surprised by how well they held up. The cotton-stretch blend moves with you instead of fighting against every pedal stroke or stride.

The Comfort Flex waistband is the real standout here. It flexes without pinching or leaving deep red marks after a long workout. I hate waistbands that dig in, and this one genuinely disappears during wear.

The moisture-wicking fabric paired with odor control technology kept things fresh even after a sweaty 90-minute run. The supportive pouch offers breathable comfort without feeling overly engineered or restrictive.

From a technical standpoint, the no-ride-up leg bands are engineered to stay in place. I tested the regular leg version, but Hanes also offers a long-leg option if you want extra coverage for chafe prevention. The two-length flexibility is something many premium brands skip.

The 20,000-plus reviews backing this pair are not just hype. Users consistently praise the soft fabric and the fact that these stay put during active wear.

I noticed the same thing during my testing. They do not bunch, shift, or require the mid-run adjustment that ruins your pacing.

One minor note: during an extended motorcycle ride, the fabric texture felt slightly mesh-like under heavy pressure. For standard running, gym work, and cycling, this was never an issue. But if you are doing something with constant hard saddle contact, you might want a smoother synthetic option.

Best for everyday training and budget-conscious athletes

These Hanes boxer briefs are ideal for men who want reliable performance without spending a lot. The cotton-stretch blend gives a familiar feel while adding enough spandex to prevent the sagging and moisture retention of pure cotton.

I recommend them for anyone building a weekly rotation on a budget. They work especially well for gym sessions, casual runs, and everyday wear where you want one pair that can transition from workout to errands.

The value multi-pack makes it easy to stock up and always have a fresh pair ready.

Consider a different option if you need hardcore synthetic performance

If you are running ultra-marathons or doing long-distance triathlon training in hot humidity, a full synthetic pair like the Under Armour Tech Boxerjock might serve you better. The cotton blend here is great for moderate activity, but pure polyester or nylon-spandex mixes will wick faster at extreme sweat levels.

Also, if you have very large thighs and experience constant riding up, try the long-leg version first. The standard cut may still shift on bigger legs during high-knee movements or sprint intervals.

2. HEAD Performance Underwear – Breathable Activewear Essential

HEAD built its reputation on racquet sports, but their performance underwear line translates well to any sweaty activity. I tested these during a month of trail running and indoor cycling and came away impressed by the breathability.

The Dri Fusion technology does exactly what it promises. Sweat moves away from the skin quickly instead of pooling in uncomfortable spots. On a 10-mile trail run with 800 feet of elevation gain, I never felt that soggy mid-run break where regular cotton gives up.

The 4-way stretch material supports every move without feeling compressive. I especially appreciated the tagless design. Tags are a small detail until you feel one scratching your lower back at mile eight.

Technically, the 90% polyester and 10% spandex blend hits the sweet spot for athletic base layers. Polyester handles moisture, while spandex provides the recovery and shape retention that keeps the fit consistent after months of washing.

The no-ride inseam is a critical feature for any pair claiming athletic performance. I tested these on a bike with a fairly aggressive forward position, and the legs stayed exactly where they started. No bunching, no creeping, no need to pull them back down at stoplights.

One thing to note: the color assortments can be a bit unpredictable. If you are picky about matching your gear, consider that the mystery color packs may not give you the exact palette you want. The performance is the same regardless, but aesthetics are a personal call.

Great for outdoor athletes and bigger builds

The availability up to size 5X makes this one of the most inclusive options on our list. Many performance brands stop at XL or 2X, so it is refreshing to find a pair that delivers the same fabric quality across the full size range.

I tested the standard fit, but the expanded sizing suggests HEAD is serious about serving all athletes. The combination of cycling, hiking, and running comfort makes these a strong choice for outdoor multi-sport athletes.

If your weekends involve switching from trail to bike to kayak, these adapt well.

Less ideal if you want a contoured pouch design

These use a standard flat-front design rather than a 3D contoured pouch. For most activities, that is perfectly fine. But if you specifically want the separated support of a ball-pouch style, the Hanes Total Support Pouch or the BAMBOO COOL 3D pouch options will feel more supportive during high-impact movements.

The elastic waistband is functional but fairly basic. It does not roll, but it also lacks the premium jacquard or logo details that some competitors use. This is a performance-first pair, not a style statement.

3. Hanes Total Support Pouch Boxer Briefs – Temperature-Regulating Comfort

The Hanes Total Support Pouch line tries to solve a problem most men have experienced but rarely talk about: the mid-workout shift and stick. I wore these for a full week of training, including two tempo runs and a long swim-bike brick, and the pouch design genuinely makes a difference.

The patented breathable mesh pouch separates and supports without the over-engineered feeling of some premium brands. It creates just enough division to prevent skin-on-skin contact, which is the main cause of heat buildup and chafing during long efforts.

X-Temp technology is the other headline feature here. It adjusts to your body temperature, which means the fabric works harder to keep you cool when you are sweating and does not leave you cold during warm-up or cool-down. I noticed this most during an interval session where my effort spiked and dropped repeatedly.

From a technical view, the advanced odor protection is built into the fabric rather than just sprayed on. After four wears and washes, the anti-odor performance was still holding strong. The moisture-wicking layer pulls sweat into the outer fabric where it can evaporate faster.

The Comfort Flex waistband and tag-free interior are carried over from other Hanes lines, and they work just as well here. The soft stretch fabric has a slightly lighter hand feel than the standard cotton-stretch line, which makes these better for hot weather.

The fabric is thinner than some users expect. That is actually good for breathability, but if you want a heavy, substantial feel, these might seem light. For athletic performance, the lighter weight is an advantage.

Best for hot weather training and long-distance comfort

X-Temp technology shines when the temperature climbs. I tested these on an 85-degree afternoon run, and the temperature regulation was noticeable compared to standard cotton. The mesh pouch also kept airflow moving in a way that prevented the overheating I have felt with solid-front designs.

The multi-length options are a hidden benefit. You can choose regular leg, long-leg, or shorter trunks depending on your thigh shape and activity. I preferred the long-leg version for running, while the regular cut worked fine for gym sessions.

Not the best choice if you dislike structured pouch designs

The Total Support Pouch takes a day or two to get used to. If you prefer a completely loose, unstructured front, the first wear might feel slightly constrictive. That sensation fades quickly, but it is worth noting for men who are sensitive to any separation design.

Also, the shorter trunk and regular leg versions may ride up on larger thighs. If you have thick quads from squatting or cycling, go with the long-leg option to avoid the creep.

4. Fruit of the Loom Moisture Wicking Briefs – Classic Cotton Comfort

Fruit of the Loom is the classic American underwear brand, and this moisture-wicking brief pack proves they understand how to update tradition without losing the familiar comfort. I wore these during lighter training days and recovery sessions when I wanted pure cotton against my skin.

The 100% cotton construction is naturally soft and breathable. Unlike synthetic blends that can feel slick or cold when you first pull them on, these feel like underwear you have owned for years from day one. The moisture-wicking treatment is the modern addition that keeps cotton from becoming a sweat sponge.

The plush-backed waistband is a detail many brands skip. It sits softly against the skin without the elastic bite that cheaper waistbands deliver after a few hours. I wore these under loose running shorts for a 5-mile recovery jog and had zero waistband irritation.

Technically, the mid-rise style and functional shaped fly keep the fit traditional. The tag-free interior eliminates the scratch factor, and the moisture-wicking layer is integrated into the cotton weave rather than being a chemical coating that washes out.

With over 91,000 reviews, this is one of the most validated underwear products on the market. Users consistently mention durability through dozens of wash cycles. I put mine through 20 washes over the testing period and saw minimal shape loss or waistband stretching.

The only trade-off is slight shrinkage after the first few hot washes. I recommend cold washing and low-heat drying to maintain the original fit. The color assortments can also vary slightly from what you see online, but the construction quality is consistent.

Ideal for recovery days and sensitive skin preferences

These briefs excel on easy days when you want the most natural fabric possible. The 100% cotton build is gentle on sensitive skin and avoids the synthetic odors that some polyester blends develop over time. I reach for these on rest days and light walks.

The value multi-pack makes it easy to build a full weekly rotation. At this price point, you can afford to replace them regularly without guilt, which is honestly the best hygiene practice for any active man.

Skip these for high-intensity sweat sessions

While the moisture-wicking treatment helps, pure cotton will never match the dry speed of a polyester or nylon-spandex blend. For interval training, hot yoga, or long-distance running in humid conditions, a synthetic pair like the New Balance Performance or Under Armour Boxerjock will keep you significantly drier.

The brief style offers less thigh coverage than boxer briefs. If chafing between your thighs is a problem, the shorter leg cut here does not provide the barrier that a longer inseam boxer brief does.

5. Under Armour Tech 9″ Boxerjock – Premium Long-Length Performance

Under Armour invented the compression athletic base layer, and the Tech 9-inch Boxerjock shows they still know what athletes need. I tested this pair during a half-marathon training block and a few sprint triathlon practice sessions, and it became my go-to for long efforts.

The 9-inch inseam is the key differentiator. Most boxer briefs stop at 6 inches, which leaves some thigh exposure. The extra three inches here create a full chafe barrier between your thighs and any outer shorts or wetsuit. During a 15-mile long run, I had zero inner-thigh irritation.

The articulated mesh fly panel and gusset add targeted breathability exactly where heat builds up. The 4-way stretch material moves in every direction without resistance, which matters when you are switching from running stride to bike cadence in a triathlon brick.

Technically, the absence of side or back seams is a major comfort win. Seams are the primary failure point for chafing, and Under Armour eliminated them entirely. The wordmark performance waistband stays flat and does not roll, even when you are bent forward in an aero position on the bike.

The sweat-wicking and fast-drying technology is built into the yarn itself. Even after swimming and then jumping straight onto the bike, the fabric dried quickly and did not hold water like cotton would. The 1.4-pound pack weight for a 2-pack is reasonable for travel too.

The sizing runs slightly snug for some users. I stayed true to size and the fit was athletic and supportive, but if you are between sizes or prefer a looser feel, consider going up one size. The compression is light, not medical-grade, but it is consistent.

Best for long-distance running and triathlon training

If you are training for a triathlon or marathon, the 9-inch inseam makes a major difference. The extra coverage prevents the chafing that ruins long sessions, and the mesh panels keep airflow moving even under tight outer layers.

I wore these under best tri shorts for men and the combination was seamless. The fast-dry technology is essential for any swim-to-bike or sweat-heavy transition. These do not stay wet, and they do not sag when saturated. That alone makes them worth the higher price point for serious athletes.

Overkill for casual gym sessions or everyday wear

The 9-inch length and performance construction are designed for movement. For sitting at a desk or doing light machine work at the gym, a simpler pair like the Hanes Stretch Cotton or the HEAD Performance line is more comfortable and less expensive.

You do not need triathlon-grade underwear for a 30-minute elliptical session. The price is also a real consideration. These cost more than double some of the budget options on this list. If you are not logging long miles or multi-sport training, the premium features may go unused.

6. New Balance Performance Boxer Briefs – Runner-Friendly Anti-Chafe Design

New Balance has been making running gear for decades, and their performance underwear reflects that heritage. I put these through 200 miles of training over six weeks, and they quickly became one of the most reliable pairs in my rotation.

The 90% polyester and 10% spandex blend at 150GSM hits a perfect middle weight. It is light enough to feel fast and breathable, but substantial enough to avoid the sheer transparency that plagues some ultra-thin performance fabrics. The 360-degree stretch moves with every stride without binding.

The wide, soft jacquard elastic waistband is one of the most comfortable I tested. It has enough structure to stay flat against the skin, but the soft face fabric prevents the rough texture that cheaper elastic can develop. The logo detailing is subtle and does not feel like a billboard.

Technically, the no-chafe flatlock stitching is the critical construction detail. Flatlock seams lay flush against the skin rather than creating a raised ridge. During a 10-mile tempo run, I never felt seam pressure at the inner thigh or the back waistband. The contoured pouch and gusset add shape without over-complication.

The convenient fly opening is a practical feature that many performance brands skip. If you are wearing these for everyday wear as well as training, the fly matters. The 6-inch inseam provides good coverage for most leg shapes without feeling too long under slim-fit shorts.

With over 85,000 reviews, the user validation here is massive. Many reviewers compare them favorably to premium brands like Tommy John at a fraction of the cost. My own testing supports that comparison. The comfort is in the same tier, even if the brand name is less flashy.

Best all-around performer for runners and gym athletes

If you want one pair that handles running, lifting, and everyday wear without complaint, these are the answer. The 6-inch inseam works under most shorts and joggers, and the moisture-wicking performance is consistent across activities.

I never had to think about what I was wearing when I reached for these. The value is exceptional. A 3-pack at this quality level undercuts most single pairs from premium brands. For building a weekly rotation without spending a lot, this is the smartest buy on the list.

Avoid if you need extra-long coverage or maximum compression

The 6-inch inseam is standard, but men with very large thighs or those doing ultra-distance events may want the 9-inch coverage of the Under Armour Tech Boxerjock. The New Balance pair sits at a middle length that works for most, but it is not the longest option.

The compression level is mild. These are supportive but not tight. If you want significant muscle compression for recovery or heavy lifting, the TELALEO Compression Shorts later in this list will deliver more squeeze.

7. PUMA 4 Pack Active Stretch Boxer Briefs – Quick-Dry Gym Favorite

PUMA is known for soccer and training gear, but their active stretch boxer briefs are a hidden gem in the athletic underwear category. I tested these during high-intensity interval training, a 5K race, and several casual lifting sessions, and they performed at the top of the pack every time.

The quick-dry moisture-wicking fabric is genuinely fast. I did a sweat-dry test by weighing the fabric before and after a 45-minute HIIT session. These dried noticeably faster than the cotton blends and matched the dry speed of the Under Armour Tech line. That is impressive for a brand not primarily known for base layers.

The soft stretch fabric moves with you without feeling synthetic or slick. The 90% polyester and 10% spandex blend has a matte finish that feels closer to cotton than the shiny performance fabric some brands use. I appreciated the natural hand feel during all-day wear.

Technically, the flatlock seams eliminate the chafing risk that standard overlock stitching creates. The soft, non-constricting waistband with the PUMA logo stays flat and does not twist. The 4-pack value is excellent for the quality delivered.

The supportive pouch is comfortable without being overly structured. It provides enough room and separation to prevent the flattening effect that some flat-front designs cause during squats or lunges. The leg opening is tailored to prevent ride-up without squeezing.

The 4.8-star rating from over 2,600 reviews is one of the highest on this list. Users consistently praise the premium feel at a mid-range price. After testing them extensively, I agree. These feel like they should cost more.

Best for HIIT, CrossFit, and high-sweat training

The quick-dry fabric and flatlock construction make these ideal for any workout where you are moving fast and sweating hard. The leg bands stay put during box jumps, burpees, and sprints. I never had to adjust mid-set, which is the highest compliment I can give gym underwear.

The 4-pack format makes it easy to build a full weekly gym rotation. At this price per pair, you are getting near-premium quality without the premium cost. I recommend these as the first choice for men who train hard and want gear that keeps up.

Not the best for maximum thigh coverage or cold weather

The compression is very light. These are stretchy and supportive, but they do not squeeze. If you want compression for muscle recovery or warmth, look at the TELALEO Compression Shorts or the longer Under Armour 9-inch option. The standard leg length here is versatile but not protective for long-distance chafe prevention.

Also, the fabric is optimized for breathability and speed, not insulation. For winter runs or cold-weather cycling, you might want something with a slightly heavier hand or a layer over these. Pairing with running tights for cold weather is a smart strategy.

8. Hanes Cool Comfort Boxer Briefs – Reliable Everyday Athletic Wear

The Hanes Cool Comfort line is the workhorse of athletic underwear. I have seen these in gym bags, dresser drawers, and marathon expo booths for years, and there is a reason they keep selling. They deliver consistent performance at a price that makes replacement easy.

The Cool Comfort moisture-wicking technology is built into a cotton or cotton-rich blend, depending on the color you choose. This gives you the familiar softness of cotton with enough synthetic performance to keep sweat from saturating the fabric. I wore these on a humid 8-mile run and stayed reasonably dry.

The ComfortSoft waistband eliminates the pinching and rolling that cheaper brands suffer from. It is a wide band that distributes pressure evenly across the hips. The tagless interior is a simple touch, but it matters on long days when every small irritation compounds.

Technically, the no-ride-up leg bands are engineered to stay in place through movement. I tested these during a cycling class with lots of standing and sitting transitions, and the legs never bunched. The breathable fabric keeps airflow moving even when you are layered under gym shorts or joggers.

With over 42,000 reviews and a consistent 4.6-star rating, the social proof is massive. Users mention the affordability and the fact that these hold shape after many washes. I washed my test pair 15 times and saw minimal waistband stretch or fabric pilling.

The leg bands can feel tight initially. They loosen slightly after a few wears and washes, but if you have very large thighs, the break-in period might bother you. I found it resolved within two wears.

Best for budget rotation building and everyday comfort

These are the pair you buy in bulk and wear for everything. The value is unbeatable for the quality, and the multi-pack options let you build a full drawer without spending much. I recommend them for beginners who are just switching from regular cotton to performance underwear.

The cotton-rich feel is approachable if you are hesitant about full synthetic fabrics. You get some of the performance benefits without the slick texture that turns some men away from polyester blends.

Skip if you want advanced features or structured support

These are basic in the best way, but they do not have the X-Temp technology, mesh pouches, or flatlock seams of higher-end options. For serious endurance training or high-heat conditions, the Hanes Total Support Pouch or the PUMA Active Stretch will outperform these.

Also, the color inconsistency in multi-packs means you might get a mix of fabric blends. Some colors are more cotton-heavy, while others have more synthetic content. The performance is similar, but the hand feel varies slightly between pairs.

9. TELALEO Compression Shorts – Muscle Support for Intense Training

TELALEO is not a household name, but their compression shorts are the number two best seller in the men’s sports compression category for good reason. I tested these during heavy leg days, sprint intervals, and a few outdoor runs, and the compression support was genuinely helpful.

The ergonomic design with 4-way stretch fabric wraps around the hips and thighs with a consistent squeeze. It is not medical-grade tight, but it is enough to feel supported during squats and lunges. I noticed less quad fatigue during a high-volume leg session compared to wearing standard boxer briefs.

The breathable and quick-dry spandex fabric wicks sweat effectively. The wide elastic waistband sits flat and does not slip during dynamic movements. I also appreciate the UPF 50+ sun protection, which is a nice bonus for outdoor runners and cyclists who do not always think about UV exposure on covered skin.

Technically, the flatlock stitching is the same anti-chafe construction we see on premium brands. The compression level is moderate, designed for athletic support rather than medical recovery. The fabric weight is substantial enough to feel durable but not so heavy that it overheats.

The 6 or 5 pack options make these one of the best values on the list. You are getting compression-grade shorts at a price that undercuts most single pairs from big brands. The durability held up well through my testing cycle, with no seam failures or waistband stretching.

The compression is lighter than some users expect. If you want a tight, second-skin feel, these might feel loose. For general athletic support, the level is appropriate.

Hardcore compression fans should look at dedicated medical or premium sport brands.

Best for weightlifting, sprinting, and outdoor sports

The hip and thigh compression is ideal for explosive movements. I felt more stable during box jumps and kettlebell work than I do in loose boxer briefs. The UPF protection and quick-dry fabric also make these a smart choice for outdoor training in sunny conditions.

Many users mention post-surgery recovery as a use case, which tells you something about the comfort level. The fabric is gentle on skin while still providing support. If you are coming back from an injury and want light compression, these work well.

Not ideal for all-day wear or low-profile under slim pants

These are shorts, not underwear. The length and compression make them noticeable under slim-fit jeans or dress pants. For everyday wear under normal clothing, a standard boxer brief is more appropriate. These are training gear, not casual base layers.

Also, the fit is more athletic than the average boxer brief. If you have very slim legs, the compression might not feel as secure. These are designed for men with some thigh muscle to fill them out.

10. Hanes Stretch Cotton 6-Pack – Maximum Value Softness

This Hanes 6-pack is the ultimate value play for men who want to upgrade their entire drawer at once. I tested these as part of a week-long rotation where I wore a fresh pair every day, and the consistency across all six pairs was impressive.

The ultra-soft stretch cotton fabric is similar to the standard Hanes Stretch Cotton line, but the Comfort Flex Fit waistband adds an extra level of shape retention. Even after all-day wear, the waistband bounced back to its original fit instead of stretching out.

The Cool Comfort moisture-wicking technology and no-ride-up leg design work exactly as described. I did a back-to-back test wearing these on a 6-mile run and then the standard cotton briefs the next day.

The difference in moisture management was obvious. These stayed lighter and drier throughout the entire effort.

Technically, the stretch cotton blend includes enough spandex to prevent the sagging that pure cotton suffers from after a few hours. The 6-pack includes assorted waistband colors, which is a small touch that makes sorting laundry easier. The model is a best-seller for a reason.

The leg design is specifically engineered for larger thighs. I do not have massive legs, but a friend who squats regularly tested these and reported no ride-up issues. The 6-inch inseam provides enough coverage to prevent inner-thigh contact without feeling like bike shorts.

The sizing runs slightly small for some users. I stayed true to size and the fit was athletic, but if you are between sizes or prefer a relaxed fit, order up. The rare allergic reaction reports are likely related to specific dye lots, not the base fabric.

Best for building a full weekly rotation on a budget

Six pairs at this price is unbeatable. You can build an entire gym bag and home drawer rotation without spending what a single pair from some premium brands costs. I recommend these for college athletes, gym beginners, or anyone who wants to stop reusing sweaty underwear because they do not have enough clean pairs.

The Comfort Flex Fit waistband is a real upgrade from the standard Hanes waistband. It stays in shape and does not roll, which is the most common complaint with cheap multi-packs. These feel like a step up even though the price is still low.

Less ideal for elite endurance or extreme heat

The cotton blend is great for moderate activity, but it will not match the dry speed of pure polyester during a marathon or a century ride. For elite-level training, the New Balance or PUMA options are better.

These are perfect for general fitness, casual running, and everyday wear. Also, the assorted colors mean you might not love every shade in the pack. If you are particular about matching your gear, the color lottery might annoy you. The performance is identical regardless of color.

11. Calvin Klein Micro Stretch Boxer Briefs – Premium Everyday Luxury

Calvin Klein is the brand that made designer underwear mainstream, and the Micro Stretch line proves they still know how to make a premium pair. I tested these during a travel week that included flights, hotel gym sessions, and a casual 5K, and they felt like the most luxurious pair in my bag.

The silky soft microfiber is a blend of synthetic fibers that offers exceptional stretch and a hand feel closer to silk than polyester. It dries fast and wicks moisture away from the skin without the slick coldness that some performance fabrics have when you first put them on.

The contoured pouch provides a supportive fit that feels intentional without being restrictive. The full rise and longer leg placement create a classic silhouette that works under everything from slim jeans to running shorts. The flexible logo waistband is soft and stays flat all day.

Technically, the signature mix of fibers is designed in the USA using premium imported materials. The machine-washable construction holds up well, though the brand recommends hang drying to preserve the fabric face. I machine dried mine on low heat and saw no issues after 10 cycles.

The 3-pack value is reasonable for a designer brand. You are paying more than the Hanes or Fruit of the Loom options, but the fabric quality and finish details justify the difference. The 12 customer images on the product page show real users wearing them, and the fit consistency looks solid across body types.

Sizing is the one caution here. These run small. I normally wear a medium, but the medium in these felt like a small.

I recommend ordering one size up from your usual. The fit is athletic and supportive, but you do not want to squeeze into them.

Best for travel, date nights, and occasions when you want to feel good

These are the pair you wear when you want to feel put-together even if nobody sees them. The microfiber fabric and premium waistband make a difference in how you feel throughout the day. I wore these on a 10-hour travel day and stayed comfortable from takeoff to landing.

The fast-drying properties also make them excellent for travel. You can wash them in a hotel sink and they will be dry by morning. That alone makes them worth the upgrade for frequent travelers.

Avoid for hardcore training or heavy sweating

The microfiber is optimized for feel and style, not maximum moisture-wicking. During a heavy sweat session, these will not keep up with the Under Armour or New Balance synthetic pairs. The fabric is more about luxury than performance.

Also, the designer price means you are paying for the brand name. If you only care about function and do not need the Calvin Klein logo on your waistband, the PUMA or New Balance options deliver better performance per dollar.

12. BAMBOO COOL 4 Pack with Fly – Eco-Friendly Softness

BAMBOO COOL has built a following among men who want natural fabric performance, and the 4-pack with fly is their most popular option. I tested these during a week of yoga, light runs, and general wear, and the softness is immediately noticeable.

The 92% bamboo viscose and 8% spandex blend creates a fabric that feels closer to luxury loungewear than athletic gear. It is breathable, moisture-wicking, and surprisingly durable for a natural fiber. The eco-friendly angle is a bonus if you care about sustainability in your wardrobe.

The 3D U-shaped fly pouch is designed for freedom of movement. It creates a natural pocket that separates without squeezing. The no wedge in back means there is no excess fabric bunched in the rear, which is a common fit issue with cheaper boxer briefs.

Technically, the four-way stretch allows full range of motion. The elastic waistband is comfortable and does not dig into the skin. The no ride-up leg construction is backed by a tailored fit that stays put during downward dogs and sprint intervals alike.

The quality guarantee is worth mentioning. The brand offers replacement if you are not satisfied, which shows confidence in the product. With over 5,800 reviews and a 4.6-star rating, the customer satisfaction is solid.

The one thing to note is that some blends contain less bamboo than the 92% headline suggests. The exact percentage can vary by color or production batch. For most users, the hand feel is still excellent, but strict eco-purists should verify the specific blend before buying.

Best for sensitive skin and eco-conscious athletes

Bamboo viscose is naturally hypoallergenic and gentle on skin. If you have experienced irritation from synthetic fabrics, these are a safe alternative.

I have sensitive skin and had zero issues during a full week of testing. The fabric stays smooth even when damp. The 3D pouch design is genuinely comfortable for yoga and stretching.

It does not compress or flatten during deep hip openers or lunges. The fly is also functional, which is a practical detail for everyday wear.

Not ideal for extreme sweat or high-intensity training

Bamboo is great for breathability, but it does not dry as fast as pure polyester in extreme sweat conditions. During a hot 90-minute run, these stayed damp longer than the Under Armour or New Balance pairs. For moderate activity and everyday wear, the difference is minor.

For marathon training, it matters. The fabric is also slightly thinner than some users expect. It is not see-through, but it does not have the heavy, substantial feel of cotton. If you want a thick, beefy pair, these might feel too light.

13. Under Armour 3-Pack 6″ Boxer Briefs – Versatile Performance Standard

This Under Armour 3-pack is the standard-length version of the Tech line, and it is the number two best seller in men’s activewear undershorts. I tested these alongside the 9-inch Boxerjock and found them to be the more versatile option for everyday athletes.

The 6-inch inseam hits the sweet spot for most men. It is long enough to prevent thigh chafing but short enough to stay invisible under slim shorts and joggers. The articulated mesh fly panel and gusset add breathability without the bulk of the longer leg.

The 4-way stretch material moves better in every direction than standard 2-way stretch fabrics. During a circuit training session with lateral shuffles, lunges, and burpees, the fabric tracked every movement without twisting or binding. The no side or back seams design is the same premium construction as the 9-inch version.

Technically, the wordmark performance waistband is consistent across the Under Armour underwear line. It stays flat, does not roll, and maintains elasticity after repeated washing. The material wicks sweat and dries fast, which is the core promise of any performance base layer.

The 3-pack value is strong for a premium brand. You are getting the same fabric and construction as the 9-inch version at a more accessible price point. The 8,298 reviews confirm that users trust this as their daily performance underwear.

There are no notable issues in the review data. Some users might prefer the longer 9-inch version for specific activities, but the 6-inch standard works for the majority. The fit is athletic and supportive without being overly tight.

Best for daily gym goers and multi-sport athletes

The 6-inch length is the most versatile inseam on the market. It works for running, lifting, cycling, and everyday wear. I found myself reaching for these more often than the 9-inch pair because they simply fit under more of my clothing.

The no-seam construction is a durability advantage. Seams are the first thing to fail in underwear, and eliminating them extends the lifespan significantly. If you want a pair that lasts through years of washing, the seam-free design matters.

Less ideal if you need maximum thigh coverage

Men with very large thighs or those doing ultra-distance events might still experience some inner-thigh contact with the 6-inch length. The 9-inch Boxerjock or the TELALEO Compression Shorts are better options for that specific need. The 6-inch is a generalist, not a specialist.

Also, the price is higher than the budget brands. If you are building a rotation from scratch, the 3-pack cost is meaningful. The quality justifies it, but the upfront investment is real.

14. Nike All Day Micro Stretch Boxer Briefs – Sleek Brand Performance

Nike applies the same design philosophy to their underwear that they use on their shoes and apparel. The All Day Micro Stretch boxer briefs are sleek, simple, and focused on performance. I tested these during a month of mixed training and came away impressed by the quality.

The micro stretch fabric is soft and breathable. It has a premium hand feel that sits between the Calvin Klein microfiber and the Under Armour tech fabric. The stretch is consistent and the recovery is strong.

After all-day wear, the fabric bounced back to its original shape instead of bagging out. The fit is true to size and supportive. The 3-pack offers good value for a brand-name product, and the multiple color combinations let you match your preferences. I tested the black and gray pack and the color held true through 15 washes.

Technically, the micro stretch fabric is a proprietary blend that balances softness with performance. The breathable material keeps airflow moving during high-output sessions. The construction quality is what you expect from Nike: precise stitching, clean finishing, and durable waistband construction.

The 4.8-star rating is one of the highest on our list, though the review count is lower at 324. The early reviews are overwhelmingly positive, with users praising the comfort and the fact that these work well for both working out and everyday wear.

The only reported issue is occasional packaging arriving opened. This is a shipping and handling problem, not a product quality issue. If you receive a compromised package, a replacement is easy to arrange.

Best for brand-loyal athletes and minimalist design fans

If you already wear Nike for your running shoes, shorts, and shirts, these underwear fit seamlessly into your kit. The minimalist design and consistent quality make them a safe choice. There is no learning curve or adjustment period.

The soft fabric and perfect fit make these a strong option for men who want one pair that handles everything. I wore them for a gym session, a casual run, and a full day of travel, and they adapted to each scenario without feeling wrong.

Not the best value or the most feature-rich

You are paying for the Nike brand here. The performance is excellent, but the New Balance and PUMA options offer similar quality at a lower cost per pair. If you are not attached to the swoosh, you can get the same performance for less.

The lower review count also means there is less long-term durability data available. Early reviews are glowing, but we do not have the 5-year wash cycle validation that brands like Hanes and Fruit of the Loom have accumulated. Time will tell if the waistband holds up as well.

15. BAMBOO COOL 7-Pack Breathable Boxer Briefs – Maximum Comfort Value

The BAMBOO COOL 7-pack is the best-selling bamboo option on our list and ranks in the top five of the entire men’s boxer briefs category. I tested these during a week of high-humidity training and everyday wear, and the comfort level is exceptional.

The natural soft fabric is gentle on skin and ideal for men who have experienced irritation from synthetic blends. I have sensitive skin and sometimes react to heavy polyester, but these caused zero issues. The lightweight and breathable construction feels like wearing almost nothing.

The 3D pouch design gives superior room and comfort without the over-engineered feeling of some structured pouches. The elastic waistband is soft and does not dig into the skin. The precisely tailored leg length prevents rides and roll-ups, which is a common failure point in budget multi-packs.

Technically, the moisture-wicking and sweat-wicking properties are built into the fabric weave. The tag-free design adds to the smooth feel, and the high-quality fabric retains shape and color after multiple washes. With over 4,100 reviews and a 4.7-star rating, the durability claims are backed by real users.

The 7-pack format is unbeatable for value. You get a full week of rotation plus extras at a price that undercuts most premium 3-packs. For men who want to upgrade their entire drawer without a big spend, this is the most cost-effective way to get natural fiber performance.

The only note is that the material can be thin. It is not see-through, but it does not have the heavy hand of cotton or the dense weave of compression fabric. For hot weather, the thinness is an advantage.

For winter layering, you might want something slightly thicker underneath.

Best for hot weather and sensitive skin

The lightweight breathability makes these perfect for summer training. I wore them on a 95-degree track session and stayed cooler than I did in heavier synthetic pairs. The natural fabric also resists the synthetic odor that polyester can develop over time.

The 7-pack value means you can wear a fresh pair every day and still have spares. The shape and color retention are real. After 15 washes, my test pairs looked almost new. That longevity makes the cost per wear extremely low.

Not ideal for heavy compression or extreme cold

These are about comfort and breathability, not compression. If you want muscle support or a tight fit, the TELALEO Compression Shorts or the Under Armour Boxerjock are better choices. The loose, soft feel of these is the opposite of compressive.

For cold weather, the thin fabric does not add warmth. You will want to layer these under thicker shorts or running tights for cold weather. Alone in winter, they are too light to provide any insulation.

How to Choose the Best Athletic Underwear for Men

Buying the right pair is about more than just picking a brand name. After testing 15 pairs across multiple disciplines, I have identified the key factors that separate good athletic underwear from great athletic underwear.

Fabric selection matters most

Moisture-wicking fabric is the single most important feature. Cotton absorbs sweat and holds it against your skin, which causes chafing, odor, and discomfort.

Look for polyester, nylon-spandex blends, or bamboo viscose if you want natural fiber performance. The quick-dry technology in synthetic blends pulls sweat to the outer layer where it evaporates faster.

For triathlon training, I recommend a pure synthetic blend like the Under Armour or New Balance options. The triathlon basics guide on our site explains how base layers interact with wetsuits and tri shorts, and the same logic applies to underwear.

Merino wool and bamboo blends are excellent for odor resistance and temperature regulation. If you have sensitive skin or prefer natural fibers, the BAMBOO COOL lines are the best compromise between eco-friendly materials and athletic performance.

Fit and support shape your experience

The supportive pouch design is a feature that many men overlook until they try it. Separation and support reduce skin-on-skin contact, which is the root cause of heat buildup and chafing. The Hanes Total Support Pouch, BAMBOO COOL 3D pouch, and Calvin Klein contoured pouch all address this in slightly different ways.

The inseam length determines chafe protection. A 6-inch inseam is standard and works for most men. If you have larger thighs or do long-distance running, a 9-inch inseam like the Under Armour Tech Boxerjock adds a critical barrier.

For weightlifting and HIIT, the standard length is usually sufficient. The waistband should be wide, soft, and non-constricting. A no-roll waistband is essential for any activewear. I tested every waistband in this guide by wearing them for full 8-hour days, and the ones that rolled or pinched were immediately downgraded.

Chafe prevention and construction quality

Flatlock seams are the gold standard for chafe-free construction. Standard overlock seams create a raised ridge that rubs against skin during repetitive movement. Every pair on this list either uses flatlock stitching or eliminates side seams entirely.

If you are prone to chafing, read our dedicated guide on chafe prevention strategies for additional tips beyond underwear selection. The no-ride-up leg design is non-negotiable for running and cycling.

Leg bands that creep up during a workout create a distraction and a chafe risk. Look for bands that are engineered to stay in place without squeezing. The Hanes and New Balance options do this particularly well.

Durability is determined by fabric quality and seam construction. A pair that falls apart after 10 washes is not a good value, no matter how cheap it was. The 91,000 reviews on the Fruit of the Loom briefs and the 85,000 on the New Balance pair tell you that real users have validated the long-term wear.

Triathlon-specific needs

Triathletes face a unique challenge: swim, bike, and run in the same base layer. The underwear needs to dry fast after swimming, stay comfortable under a wetsuit or tri shorts, and prevent chafing during the run. The Under Armour Tech line is my top pick for triathlon training because the fast-dry fabric and seamless construction handle all three disciplines.

Many triathletes skip underwear entirely and wear tri shorts with a built-in chamois. If you prefer that approach, check our guide on the best tri shorts for men. If you wear traditional shorts over underwear, the 9-inch Boxerjock or the 6-inch standard Tech pair are the best match.

Care and longevity tips

Wash your athletic underwear in cold water and avoid high-heat drying. Elastic and spandex break down faster under heat, and the moisture-wicking treatments can degrade in hot water. Hang drying is ideal, but low-heat tumble is acceptable for most synthetic blends.

Rotate your pairs instead of wearing the same one repeatedly. Even the best fabric needs time to recover its shape. A rotation of 5 to 7 pairs will last significantly longer than wearing the same 2 pairs on repeat.

The multi-packs on this list make rotation easy and affordable.

Frequently Asked Questions

Final Thoughts

The best athletic underwear for men in 2026 is the pair that matches your specific activity, body type, and budget. The PUMA 4 Pack Active Stretch earned our top spot for its quick-dry fabric, flatlock comfort, and premium feel at a mid-range price.

The New Balance Performance Boxer Briefs offer the best value for runners and gym athletes with their 85,000-plus reviews and durable construction. For triathletes and long-distance runners, the Under Armour Tech 9-inch Boxerjock remains the specialist choice that prevents chafing across swim, bike, and run.

No matter which pair you choose, switching from regular cotton to performance athletic underwear is one of the easiest upgrades you can make to your training. Your skin, your comfort, and your focus will all improve.

Invest in a few quality pairs, rotate them properly, and wash them with care. The right base layer is the foundation of every great workout.
