Athletic underwear must stay put, breathe, and wick sweat during workouts and long days. The best pairs combine stretch fabrics, flat seams, and a cut matched to your activity level. This guide narrows the field to nine pairs that actually perform across gym, run, and daily wear.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
From gym-session moisture wicking to all-day pouch support, these nine picks cover the real differences. Here is the honest breakdown of the best athletic underwear for your next training block.
Our Picks at a Glance
How To Choose The Best Athletic Underwear
Choosing the right pair depends on matching the fabric’s stretch and the cut’s length to how you actually move. A pair that’s perfect for a 5K may feel restrictive on a rest day, while a cotton-heavy pair can turn a HIIT session into a swamp.
Fabric Blend and Stretch
Look for a polyester base mixed with spandex or elastane. That spandex percentage drives the four-way stretch — the higher it goes, the more the fabric moves with your legs rather than fighting them. A 10% spandex blend offers noticeably more give than a 5% one for deep squats and lunges.
Inseam and Coverage
Inseam length is your anti-chafe armor. A 6-inch inseam gives standard coverage for daily wear and gym sessions. A 9-inch long-leg cut, like the Under Armour pick, extends further down the thigh to stop fabric from riding up during runs or cycling.

In‑Depth Reviews
1. New Balance Men’s Performance Boxer Briefs
Our pick — over 4.5★ from 7,000+ verified ratings; the strongest balance of quality and price.
The crowd-favorite blend of stretch and no-chafe stitching that owners keep reordering.
This is the pair that wins people over on that perfect middle ground. The 90% polyester and 10% spandex fabric (at 150GSM weight) gives you that lightweight feel plus a 360-degree stretch, so deep squats and long walks both feel equally unconstrained. It holds a 6-inch inseam for coverage that sits above the knee without bunching up.
What makes it stand out in a crowded category is the combination of flatlock stitching and a wide, soft jacquard elastic waistband. The flatlock seams lie flat against your skin to prevent chafing, and the wide waistband distributes pressure so it secures you all day without digging in. The moisture-wicking technology actively pulls sweat away, keeping you dry not just during workouts but through a full desk day.
The quality is the thing everyone raves about, with owners consistently praising the breathability that keeps them cool and the contoured pouch and gusset that move with natural motion. The 10% spandex gives it a more generous stretch than the PUMA option below (which uses 5% spandex), making it feel less restrictive on recovery days.
Why It Wins Fans
- Flatlock stitching prevents chafing during long wear
- Soft jacquard waistband stays secure without pinching
- Moisture-wicking fabric keeps you dry in and out of the gym
Who Might Pass
- Some buyers report sizing runs slightly varied, so check the fit guide
- Durability gets mixed feedback from very heavy daily use
Reach for this if: you want a single versatile pair that handles workouts, commutes, and everything in between without thinking about it.
Look elsewhere if: you need a super-long anti-chafe leg for marathon training — check the Under Armour long-leg instead.
2. Gildan Men’s Underwear Boxer Briefs Multipack
The soft t-shirt-comfort pair that wins on price per pair without pretending to be gym gear.
This budget pick leans on a completely different fabric philosophy. Knit from soft ring-spun cotton, it brings that favorite-t-shirt softness to your underwear drawer — a texture that polyester blends simply can’t match. It still carries moisture-wicking technology to keep you cooler than standard cotton, plus a contour pouch and elastic waistband that stays smooth against the skin.
The honest trade-off shows up in longevity. Owners mention the pair “wear out after maybe six or eight months or so,” which near-universally gets the response “that’s a fair deal for the price.” When you’re getting this many pairs for the outlay, replacing them every half-year or so is an easy pill to swallow.
Fit is a strong suit here, though sizing does run large — several owners advise ordering one size down from the chart for a proper fit. One buyer converted from briefs entirely, praising the heavier knit and perfect thigh fit with no ride-up, and noted the covered elastic waistband stays snug but comfortable even after multiple washes.
Smart money move: the best value-per-pair in this entire list, if you’re okay refreshing them every six to eight months instead of chasing years of durability.
Best fit for: someone stocking a whole drawer affordably, or buying for a teen still growing into their size.
3. PUMA Men’s Training Fit Anti-Odor 5 Pack Boxer Briefs
The gym-day pick with built-in freshness tech that fights odor at the source.
PUMA engineered this pair specifically around a problem every athlete knows: that lingering smell after a session. The Anti-Odor technology actively works to reduce unwanted odors, while the moisture-wicking fabric keeps you dry. The result is a pair that genuinely feels fresher at the end of a long day or a hard workout.
It runs on a 95% polyester and 5% spandex blend, which means less stretch than the New Balance option’s 10% spandex — so it fits more snugly and firmly rather than giving generous give. The sleek 6-inch inseam delivers a modern, tailored look that moves with your body, and flatlock seams keep the fit irritation-free.
Owners consistently describe the quality as great for the gym, with the snug fit praised as “snug in all the right places.” Since you get five pairs in the pack, it’s easy to rotate them through a full training week. Available in sizes S to XL, the performance-driven fit is designed to work across different body types.
Grab it for: gym-goers who want odor protection built into the fabric plus a complete week’s worth of pairs in one box.
Consider another if: you prioritize maximum stretch — the lower spandex content here runs firmer than rivals.
4. Champion Men’s Everyday Active Lightweight Stretch Boxer Briefs
The stay-put stretch pair that holds its place during movement, loved by wrestlers and weekend athletes.
This five-pack earns its “Everyday Active” name through fabric that balances lightweight breathability with real stretch. Owners highlight how well it stays in place — one buyer’s verdict: “I hate when the fabric rides up… these bastards stay put.” The appearance gets positive marks too, with the different colorways arriving exactly as advertised.
There’s genuine athlete credibility here. A competitive wrestler who competes at 138 and stands 5’9″ reports they’re great for the movement of MMA or wrestling, pairing well with trainers. The stretch moves with your body rather than fighting it, and the breathable, lightweight fabric keeps things cool mid-effort.
Sizing is the mixed bag to watch. Many find them true to size — a 5’11”, 200-pound buyer says the large “fit him perfectly” — while others report they run larger than expected. The consensus on feel is that they lean toward the silky side, and buyers consistently weigh in on the strong value for the price.
Solid all-rounder: high marks for quality and movement-friendly stretch, with a stay-put waistband that does its job.
Sizing note: if you’re between sizes, read the fit comments carefully — some owners found these run a touch big.
5. Calvin Klein Men’s Intense Power 3-pack Boxer Brief
The bold-logo microfiber pair that pairs modern style with a supportive U-pouch.
This is the pick when your underwear needs to look as good as it performs. It’s a bold remake of Calvin Klein’s iconic logo, made from silky soft microfiber with a wide supportive waistband. The contoured U-pouch is designed for a sleek fit that supports rather than flattens, and the unmistakable modern look carries that designer confidence.
Performance-wise, owners find them comfortable and well-fitting, with a key detail being that they don’t roll up during wear. They’re soft and breathable, with buyers calling out the quality fabric as offering great value for money. The microfiber texture feels noticeably smoother and more premium against the skin than standard athletic mesh.
The one honest caveat concerns durability. While many find the pair durable, a subset report issues with seams coming apart. If you’re hard on your gear and expect years from every pair, that’s worth weighing against the style payoff this 3-pack delivers.
The Style Angle
- Silky smooth microfiber feels premium against the skin
- Wide supportive waistband holds without rolling
- Contoured U-pouch gives a sleek modern fit
The Honest Catch
- Seam durability gets mixed reports from owners
- Premium branding means fewer pairs per pack
Choose this when: the waistband look matters and you want designer comfort that still performs in the gym.
Think twice if: you’re hardest on seams and expect workout gear to survive years of abuse.
6. Under Armour Men’s Performance Tech Mesh Long-Leg Boxerjock
The 9-inch long-leg built to end thigh chafing on long runs and heavy lifts.
This is the specialist for anyone whose thighs rub together during distance work. The 9-inch inseam extends well down the leg, providing ample coverage that stops fabric from creeping up mid-stride. It’s the longest cut in this list, and that extra length is exactly what makes it the anti-chafe champion.
The tech mesh construction delivers the all-day comfort and ultra-soft feel that Under Armour built its reputation on. Owners describe the fit as one that “never rides up on thighs,” providing coverage that stays locked in place through workouts. It’s breathable, comfortable, and buyers consistently note it prevents chafing during activity.
The key decision point is the trade-off between that protective length and daily simplicity. The long leg works brilliantly for runs, cycling, and squats, and the breathability keeps you cool during high-output sessions. Fabric quality does get mixed feedback — some owners praise it while others find it on the cheaper side — so it’s not the most luxurious feel in this lineup.
The chafe solution: if thigh ride-up ruins your runs, this 9-inch inseam is the most direct fix on this list.
skip it if: you prefer a shorter, cooler cut for daily desk wear — the extra leg coverage runs warmer.
7. Nike Men’s All Day Micro Stretch Boxer Brief (3-Pack)
The highest-rated pair here, blending Dri-FIT sweat control with an all-day stretch fit.
This Nike 3-pack carries the strongest owner approval in this entire roundup. The defining tech is Dri-FIT, which moves sweat away from your skin to keep you dry and comfortable — the same moisture management that powers Nike’s performance shirts, now applied to your base layer. The all-day comfort stretch fabric makes movement feel easy and natural.
The fit is where this pair earns its “All Day” name. Wide hems at the legs keep the underwear firmly in place, stopping the ride-up that plagues cheaper cuts. Buyers consistently find them true to size, with one owner noting they fit “perfectly in their size” and describing the material as “so nice and smooth.”
What’s notable is the durability story — one buyer calls them the go-to for “my active boys,” praising quality that holds up to constant wear and washing. The soft, smooth texture and comfortable waistband make them easy to recommend, even at a higher price point, with owners saying they’re “worth paying a bit more for comfort.”
Why It’s A Favorite
- Dri-FIT technology actively wicks sweat away
- Wide hems lock the legs in place
- True-to-size fit with soft, smooth fabric
Weigh This First
- Premium pricing puts it above most rivals per pair
- Limited to a 3-pack for the higher cost
Pick it for: the best-rated blend of sweat control, true sizing, and durability for daily athletes.
Pass if: budget per pair matters more than the Dri-FIT edge — the Gildan or Champion packs cost far less.
8. SAXX Underwear Co. Men’s Multi-Sport Mesh Boxer Brief
The patented BallPark Pouch pair engineered to kill chafing and stop constant adjustments.
SAXX built its entire reputation around solving one problem: the endless tugging and adjusting that ruins otherwise good days. The BallPark Pouch is their patented support system designed to reduce friction and keep everything comfortably in place. The Multi-Sport mesh variant adds cooling breathability specifically for high-intensity work.
The material breakdown uses Nylon, Elastane, and Polyester in the mesh construction. Owners confirm the pouch does its job — one buyer who ran 13 miles reported zero chafing, while another praised how the “pouch fits leak shields, prevents accidents.” The quick access port and stretchy-not-tight fit earn consistent praise across activity types.
The honest trade-off is durability and daily-versus-performance fit. One owner reported the pair “start falling apart in the crotch after just 3 months” despite following washing instructions. Others find daily wear less comfortable than simpler rivals, with the fabric loosening slightly when sweaty. Some buyers also recommend sizing down for the best fit.
Built for runners: the mesh cooling and BallPark support make it a standout for long, hot efforts where chafing is the enemy.
Look elsewhere for: all-day lounge comfort or if you want seams that survive a full year of hard use.
9. SAXX Underwear Co. Men’s Core Performance Mesh Boxer Brief
The versatile training pair with the same BallPark support tuned for all-day comfort.
This is SAXX’s core performance option, ranking as the “Best For Versatile training” in the lineup. It uses a Polyester and Elastane blend with the patented BallPark Pouch, plus the No-RideUp Leg and No-Roll Waistband features that keep everything locked in place. It’s built to bridge the gap between gym sessions and casual wear.
Owners consistently call it the best they’ve owned, praising the excellent fabric and its moisture-wicking properties. One buyer notes it “feels like wearing nothing at all,” while another confirms it stays in place all day without riding up. The support keeps everything comfortably secure, and the 4-way stretch construction moves with your body through any workout.
The value equation is the main split point. For some, the performance justifies the premium price; for others, it’s simply expensive. The durability picture is also mixed, so this is a pair you buy for the daily comfort experience rather than the longest possible lifespan. It’s the most expensive option here, so it needs to earn its keep.
Invest here if: you want the full SAXX experience — that “wearing nothing” feel with genuine all-day support.
Think twice if: per-pair cost dominates your decision, since cheaper options deliver solid performance for far less.
Understanding the Specs
Fabric Blend Ratio
The polyester-to-spandex ratio is the single biggest predictor of how a pair moves. Polyester drives moisture wicking and durability, while spandex provides the stretch. A 10% spandex blend gives noticeably more give than a 5% one — meaning the New Balance pair stretches more freely than the PUMA. Cotton blends trade some athletic performance for softness and warmth.
Inseam Length
Inseam length directly controls how much leg coverage you get and how much the pair resists riding up. A 6-inch inseam is the everyday standard for gym and desk wear. A 9-inch inseam, like the Under Armour long-leg, extends further down the thigh to prevent chafing during runs and cycling. More length equals more anti-chafe protection but also more fabric warmth.
