Skew fly for quick access, anatomical fit for hold without pressure, and “dry-zone” mesh curtains for real airflow. Built for motion, not for maintenance: the skewed fly is fast when you need it, and the anatomical pouch/curtains separate skin-to-skin contact to stop heat and sticking. CoolTech wicks and dries fast, while the leg binding resists ride-up during squats, sprints, or rucking. The anti-odor finish keeps you fresh even when your pace hasn’t let up. Powered by CoolTech, a lightweight, elastic, quick-dry fabric (92% polyester / 8% elastane), these Trunks wick moisture fast, provide up to 4-6°C (6-10°F) better cooling than cotton, and move with you through every session, from training to recovery.

Performance Benefits:
Pressure-free support — holds in place, adapts to body shape.
Dry-zone mesh — airflow where men need it most.
No ride-up — leg openings designed to stay put.
Odor control — antimicrobial finish for lasting freshness.
Everyday to elite — light, quick-dry comfort for training and beyond.
Tech Proof: Wicking 20-30 mm/s, drying 80-120 g/h, cooling 4-6°C better than cotton, Martindale 40-60k.

Overall rating: 4.9 / 5 from 95 reviews.

The mesh is what I was looking for. These are very comfortable and cooling. They are a good fit however I wish they were .5 inches longer on the legs. I also hope they offer a sport brief I White . I have stretch white jeans which black will show through. Also several pairs of shorts are thin. I will buy again

These are very comfortable however the sizing runs small. I am 31-32, ordered medium they fit but legs should be an inch longer. Maybe they’ll see and make adjustments

Sport Trunk, Skew Fly, Cooltech, Black

Grabbed these for my partner and he keeps telling me how breathable they are. They hug him in all the right places and the black color looks really good on him. Definitely ordering more pairs soon. 💯

Sport Trunk, Skew Fly, Cooltech, Black

Really comfortable trunks for long days. I wear them under my work pants and for evening runs, and they handle both fine. Cooling fabric actually makes a difference.

Sport Trunk, Skew Fly, Cooltech, Black

Bought these for my husband to try something cooler for his workouts. He came back from the gym saying it was the first time he didn’t have to adjust anything mid-set. The black looks sleek and doesn’t show sweat marks. Shipping was quick too, which I appreciated.

Been wearing these for basketball nights and they’re awesome. No riding up under my shorts and they dry fast after I sweat. I’m already eyeing another color.

Sport Trunk, Skew Fly, Cooltech, Black

Bought these for my boyfriend to replace some old stretched-out pairs. He mentioned right away that they stay cooler and don’t roll at the waist. The black ones look sharp on him too.

Sport Trunk, Skew Fly, Cooltech, Black

Got these for my husband and he immediately ditched his old ones. He says they’re cooler for his long shifts and I think they look great on him. Definitely grabbing another pair soon. 😊

Sport Trunk, Skew Fly, Cooltech, Black

Breathes way better than my old boxer briefs. The fly is actually convenient and doesn’t twist around. Price is a bit higher, but I can tell they’ll last.

Sport Trunk, Skew Fly, Cooltech, Black

Really impressed with this underwear. The fabric feels cool right away and doesn’t cling when I sweat. Black color still looks fresh after several washes, no loose threads or weird stretching.

Sport Trunk, Skew Fly, Cooltech, Black

I bought these for my boyfriend because he kept complaining about sweaty gym shorts. He was skeptical, but after one leg day he came home saying, “Okay, these are different.” He likes how everything stays put without feeling squeezed, and I’ll admit, the black looks really good on him. I’ve already washed them several times and they hold their shape perfectly. Now he’s telling me to replace his drawer one pair at a time.

From the Founder of MAN’s SET

“Underwear shouldn’t make your body adapt to it — it should be designed around your body. That belief is what led us to create MAN’s SET anatomical underwear. Designed around the natural shape of the male body, it provides the space, support, and freedom of movement you need throughout the day. Because true comfort isn’t just about fabric — it starts with how underwear is designed. Once you experience the difference, ordinary underwear just doesn’t feel the same.”

WHY MAN's SET?

MAN's SET is designed to fit your body perfectly, supporting the natural position of your anatomy. The patented ball pouch, engineered for movement, eliminates chafing, adapts to your shape, and provides the precise support you need for any activity.
