10 Best Underwear For Exercise in 2026

A 90% polyester and 10% spandex blend gives these boxer briefs a lightweight, 360-degree stretch that moves with you during squats, lunges, or any gym flow. The moisture-wicking technology pulls sweat away fast, so you stay dry even when things get intense. That combination of breathability and freedom makes them a go-to for anyone who wants underwear that disappears under shorts and lets them focus on the workout, not readjusting.

The flatlock stitching on these boxer briefs is designed to prevent chafing during long workouts, which is a real advantage for active guys. The contoured pouch and fly support natural movement and everyday comfort, while the 90% polyester and 10% spandex blend provides 360-degree stretch and moisture-wicking performance. For most gym-goers, this balanced design hits the sweet spot between performance and practicality.

The 4-way stretch in these boxer briefs moves with you through every squat, lunge, and stretch, so you never feel restricted mid-rep. That’s the kind of freedom that makes a big difference when you’re pushing through a tough workout. If you want underwear that stays put, breathes well, and doesn’t chafe, this is a strong option for most gym sessions. The Performance Tech fabric is designed to wick moisture, helping you stay dry during activity. It’s a solid fit for anyone who values comfort and mobility over flashy extras.

The Under Armour Performance Tech Boxer Briefs weigh 0.7 pounds, which is heavier than the 0.5-pound New Balance Performance Boxer Briefs, so if you prioritize the lightest possible feel, that difference matters. The fitted cut provides a streamlined fit that’s not too tight or too loose, and the chafe-free seams and no-roll hem keep you focused on your workout without fabric distractions.

The performance mesh fabric actively circulates air during high-output workouts, so you stay cooler and drier than standard cotton underwear. A mesh-lined pouch adds targeted ventilation where heat builds up most, and the tagless waistband with smooth stitching means no scratchy distractions when you’re deep in a squat or sprint. This pair is built for anyone who sweats hard and wants breathability without sacrificing support.

Breathability is the standout feature here: the performance mesh fabric circulates air to keep you cool and dry during high-output workouts or hot-weather training, with a mesh-lined pouch adding ventilation where it matters most. Compared to the New Balance Performance Boxer Briefs, which also wick moisture, the adidas prioritizes airflow for active use. If staying cool under pressure is your goal, this design delivers.

A 5-inch inseam and lightweight mesh fabric make these boxer briefs feel airy and unrestrictive during intense movement, so you stay cool when your workout heats up. The BallPark Pouch uses curved seams and mesh wings to lift and separate, which helps prevent that uncomfortable sticking or shifting that can ruin a good squat set. This design is ideal for anyone who values support and breathability in equal measure, especially during running, cycling, or high-rep leg days where chafing and bunching are common frustrations.

The trade-off is that the mesh construction, while excellent for ventilation, may not hold up as long under heavy friction compared to denser fabrics like those in the New Balance Performance Boxer Briefs. If you prioritize airflow and a secure, separated feel over maximum durability, this pair delivers exactly what it promises.

The 92% bamboo viscose blend is the standout feature here, it feels noticeably lighter and smoother than cotton, wicking sweat away so you stay dry through a full gym session or a long workday. That natural softness, combined with a 3D U-shaped pouch that gives everything room to sit naturally, means you won’t be adjusting yourself all day. It’s ideal for anyone who values a barely-there feel against the skin, especially if you have sensitive skin or tend to overheat during exercise.

The trade-off comes with the longer legs: while they grip without riding up, even on bigger thighs, you may need to size up if you have larger legs for a roomier fit. Compared to the New Balance Performance Boxer Briefs, which offer a more standard cotton-poly blend in a 3-pack, this bamboo option delivers superior breathability and softness but comes in a larger 7-pack, so you’re committing to more pairs upfront.

A 5-inch inseam and no-ride-up leg construction mean these boxer briefs stay put through every squat, lunge, and run, so you won’t need mid-workout adjustments. The quick-dry microfiber material keeps you cool and dry during gym workouts, training sessions, and busy days. With a supportive-but-not-too-tight athletic fit and a tagless waistband that won’t dig in, they’re built for active wear without distraction. This pair is designed for those who want to focus on their workout without worrying about their underwear.

The poly-spandex microfiber blend is synthetic, so if you prefer cotton or bamboo for everyday lounging, these might feel less breathable outside the gym. The 5-inch inseam keeps the legs from riding up during training or active days, which reviewers say stays consistent through movement. They’re suited for workouts and active wear, but if you want a single pair for both the gym and all-day wear in natural fabrics, you might look elsewhere.

A 5-pack of moisture-wicking boxer briefs means you can grab a fresh pair every workout without doing laundry midweek. PUMA built these with quick-dry polyester-spandex blend and flatlock seams, so they move with you during lunges or stretches and resist chafing on longer sessions. The tag-free waistband stays soft and non-constricting, which helps if you’re sensitive to tight bands digging in. This pack is ideal for someone who wants a reliable, no-fuss rotation for gym days and everyday wear, all in one affordable bundle.

The 5-pack gives you a full rotation of boxer briefs that wick sweat and stretch with your moves, so you stay dry and comfortable through a workout or a long day. The 90% polyester and 10% spandex blend dries quickly and resists water, which means less cling when you’re active. Flatlock seams prevent chafing, and the tag-free waistband with the PUMA logo keeps things smooth under clothes.

A six-pack gives you enough pairs for a full week of workouts without needing to do laundry. The advanced odor control technology helps keep smells in check, which is a real plus when you’re wearing these under gym shorts or during a long session. Moisture-wicking Cool Comfort fabric and X-Temp technology work together to pull sweat away and adapt to your body temperature, keeping you drier and more comfortable during exercise. These boxer briefs are designed for someone who wants reliable freshness and performance without extra fuss.

The trade-off is the fabric choice: Hanes uses a lightweight polyester stretch, which is durable and flexible, but the adidas Performance Mesh Boxer Briefs use a mesh fabric that some buyers might prefer for ventilation. If you tend to overheat during intense activity, that mesh option could feel airier on your skin. Still, the no-ride-up legs and Comfort Flex waistband keep everything locked in place, so you’re not adjusting during movement. For someone who values odor control and a big pack over maximum ventilation, this is a smart, budget-friendly pick.

A 6-inch inseam and a supportive no-fly contour pouch keep these Reebok boxer briefs from bunching or shifting under jeans, slacks or shorts, so you stay comfortable from the office to the gym. The fabric pulls sweat away from your skin, and a breathable mesh panel adds airflow where you need it most, helping you stay dry and cool through workouts and long days on your feet. That secure pouch design is ideal for anyone who hates readjusting during the day, though the no-fly means you’ll have to pull them down for bathroom breaks.

The no-fly contour pouch keeps everything securely in place without bunching or shifting, so you can focus on your workout or commute without adjusting your underwear. Reviewers note that this design prioritizes stability over quick access, meaning you’ll need to pull them down for bathroom breaks. If a locked-in feel is your priority, these deliver; if you prefer a fly for convenience, consider options that include one.

Sweat-wicking fabric pulls moisture away so you stay dry during long, sweaty sessions. Stretch material gives you full freedom of movement during lunges, sprints, or stretches. Flat seams feel smooth against your skin, reducing chafing and irritation. Wide hems help keep everything in place, so you are not constantly adjusting. This pair is built for active days where comfort and dryness matter most.

The wide hems on these boxer briefs keep the legs firmly in place during movement, so you won’t be tugging at your underwear mid-workout. Flat seams lie smooth against the skin to prevent chafing, and the stretch material lets you move freely without restriction. The sweat-wicking fabric pulls moisture away to help you stay dry, making these a reliable choice for active days.
