10 Best Workout Undies in 2026

A 90% polyester and 10% spandex blend gives these boxer briefs a lightweight feel with 360-degree stretch, so you can move freely during activity. The moisture-wicking fabric draws sweat away, and flatlock stitching helps prevent chafing. This is a performance-oriented pair that stays in place and lets you focus on your workout.

The 90% polyester and 10% spandex blend delivers 360-degree stretch and moisture wicking, so you stay dry and move freely during any activity. A wide jacquard elastic waistband with logo detailing keeps the fit secure without digging in. The contoured pouch and gusset support natural motion, while flatlock stitching prevents chafing. For someone who wants a stretchy, moisture-controlling boxer brief with anti-chafe construction, this is a reliable option.

A mesh-lined pouch and performance mesh fabric work together to keep air moving where you need it most, making these a smart pick for sweaty cardio or hot-weather training. The 5-inch inseam and stay-put legs mean less adjusting during lunges or bike intervals, while the tagless waistband and smooth stitching cut out distractions. If you run hot or log long gym sessions, this design prioritizes ventilation without sacrificing support.

The trade-off is that the mesh fabric trades some softness for that airflow, so if you prefer a plush cotton feel against your skin, the New Balance Performance Boxer Briefs offer a stretchier, softer hand. But for anyone who values breathability over cozy texture, the adidas delivers exactly what its name promises: cool, dry comfort through high-output movement. Just know the mesh is purpose-built for performance, not lounging.

A 6-inch inseam and chafe-free seams mean these briefs stay put and don’t rub, even during deep squats or long cardio sessions. The Tech Mesh fabric is insanely soft and breathable, so you get airflow where you need it most without that clammy feeling halfway through a workout. If you hate stopping to adjust or dealing with red marks afterward, this design targets exactly that problem. The 4-way stretch construction moves better in every direction, which helps when you’re lunging, reaching, or just trying to get through one more set without pulling at your waistband.

If you prefer a looser, more relaxed feel, the New Balance Men’s Performance Boxer Briefs provide a different silhouette. For anyone whose main frustration is chafing and ride-up during movement, though, this pack delivers exactly what the name promises.

The BallPark Pouch with its curved seams and mesh wings provides lift, separation, and lasting comfort, which helps during active movement. The lightweight mesh fabric keeps you cool, dry, and chafe-free during workouts, sports, travel, and everyday wear. Flat seams reduce chafe and irritation against skin, and the no-ride-up fit prevents bunching so you stay comfortable without adjusting. If you want secure support in your workout underwear, this design delivers that with a functional fly front and a 5-inch inseam.

The Core Performance Mesh boxer briefs use a lightweight, breathable mesh fabric that keeps you cool and dry during workouts, sports, travel, or everyday wear. A BallPark Pouch uses curved seams and mesh wings for lift and separation. The 5-inch inseam is shorter than some longer options, but the stretch fabric and ergonomic design prevent bunching and keep the legs from riding up. For anyone who prioritizes ventilation and a supportive pouch during active use, this is a practical choice.

The BallPark Pouch Pro adds a snug, supportive fit with anti-chafe design, making this pair ideal for active guys who want to finish a workout without adjusting or irritation.

The mesh fabric that provides breathability and moisture management is less durable than cotton, which means it may not hold up as well under frequent heavy use. The enhanced pouch offers a snug fit, but that same snugness could feel restrictive for men who prefer a looser, more relaxed cut. For those who prioritize long-term toughness over cooling performance, the New Balance Men’s Performance Boxer Briefs give a stretchier alternative, though they lack the targeted moisture-wicking and anti-chafe features of the SAXX design.

An allover mesh construction and 4-way stretch mean this pair breathes like nothing else in the guide, so you stay dry and mobile through even the sweatiest leg day. That makes it the obvious choice for hot gym sessions, outdoor runs in summer, or anyone who just runs warm and wants underwear that doesn’t trap heat. The sweat-wicking and quick-dry fabric backs that up, and the lack of side or back seams helps prevent chafing when you’re moving through squats or lunges.

The 5-inch inseam is shorter than the 6-inch inseam on Under Armour’s own Tech Mesh Brief, which some buyers may prefer for more coverage. You get only two pairs in the pack, while most competitors offer three or more for a similar outlay. If you need maximum cooling and don’t mind a smaller wardrobe rotation, this is your pick. If you want more pairs per purchase or a longer leg, the standard Under Armour Tech Mesh Brief 3-Pack gives you both.

A 92% bamboo viscose blend makes these boxer briefs lighter and smoother than cotton, wicking sweat so you stay dry through a full gym session or workday. The 3D U-shaped pouch gives everything room to sit naturally, which means fewer awkward adjustments when you’re under a barbell or climbing stairs. Long legs with flatlock seams grip without squeezing, cutting chafing between the thighs and staying put even on larger muscular legs. The fabric holds its shape wash after wash, and the reinforced crotch seam is built for daily wear.

Care is the trade-off: bamboo viscose asks for cold wash and low heat to keep that softness and avoid shrinking, so you can’t just toss it in hot like a synthetic blend. Compared to the adidas Performance Boxer Brief 3-Pack, which uses quick-dry mesh and a smaller pack size, these require a bit more laundry attention but deliver a smoother, more natural feel against sensitive skin. The 7-pack is also a bigger upfront commitment than a 3-pack, so if you’re still figuring out your preferred leg length or pouch fit, you might want to start smaller.

The quick-dry microfiber build is the standout here: the material dries fast after washing, so you can rotate through a three-pack without waiting for damp gear. That makes these boxer briefs a natural fit for anyone who sweats hard at the gym, then needs underwear ready to go again quickly. The athletic comfort fit stays supportive without squeezing, and the 5-inch inseam and no-ride-up legs mean you won’t be adjusting during squats, runs, or long days on your feet.

The adidas Microfiber Boxer Brief 3-Pack uses a quick-dry microfiber build that dries fast after washing, so you can keep your weekly rotation moving without waiting around for damp underwear. The athletic comfort fit is supportive without being too tight, built for gym sessions, training, everyday wear, and travel. A plush-soft tagless waistband and super-smooth stitching eliminate scratchy tags and rough seams, which means no distraction during long workouts or layering under clothes. The no-ride-up leg construction with a 5-inch approximate inseam keeps the legs from bunching, so the fit stays consistent through runs, reps, and active hours.

A five-pack means you can grab a fresh pair every gym session without scrambling for laundry. The moisture-wicking polyester-spandex blend pulls sweat away fast, so you stay dry through squats, lunges, or a long cardio block. Flatlock seams cut down on chafing, and the tag-free waistband avoids that annoying scratchy label. This is the set for anyone who wants reliable performance without overthinking it, just grab and go.

The fabric is 90% polyester and 10% spandex, which wicks moisture and dries quickly, great for workouts, but it lacks the natural fiber feel that some people prefer for everyday wear. Compared to other options in the guide, like the SAXX Core Performance Mesh Boxer Brief, the PUMA pack offers a straightforward design without specialized mesh. If you want a reliable rotation that handles sweat and movement, this pack works well, though it does not include a fly opening.

A six-pack of underwear for the price of most three-packs means you can stock your gym drawer without blinking. The moisture-wicking Cool Comfort fabric and X-Temp technology work together to pull sweat away and adapt to your body temperature, so you stay dry during workouts or daily wear. The Comfort Flex waistband stretches without losing shape, and the no-ride-up legs mean you aren’t tugging at your waistband between sets. For anyone building a workout wardrobe on a budget, this is the kind of practical, no-fuss gear that lets you focus on the lift instead of the laundry.

The 6-pack gives you reliable moisture-wicking performance across multiple workouts without spending extra, so you get dependable underwear that stays smooth under jeans or activewear. The lightweight polyester stretch fabric and Comfort Flex waistband move with you for total freedom and support, and the no-ride-up legs keep the briefs from bunching or shifting all day. Advanced odor control technology helps keep you feeling fresh, and the tagless design ensures a smooth, scratch-free experience.
