Made for the days cotton gives up on.
Wear one hard, then reach for the next. Which is why they come in threes.
The difference is in the pouch.
Flat-front trunks press everything against your thighs. That skin-on-skin contact traps heat and sweat. Our two-part anatomical pouch creates separation, so air can move and you stay drier and more comfortable through the day.


What men say after a long day in them.
Real men. Real results.
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.
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.
Ten-hour shifts on a warehouse floor, half of it in a forklift seat. By lunch the cotton ones used to be soaked through. These stay dry and the legs never crawl up under the coveralls.
Desk, meetings, then a train home in a wool suit. Sitting all day was always the worst part; with these the seat heat just does not build the same way. Bought my partner three more pairs.
Great for biking and hiking
Lightweight, supportive, worth the money

Heat. Movement. A day that doesn't stop.
CoolTech is a lightweight, quick-dry knit. It moves sweat off your skin instead of holding it there. That is the whole difference between one good day and one long one.
Cotton gives up. CoolTech doesn't.
Engineered more like space gear than ordinary underwear. Its technical micro-knit moves sweat away from your skin and dries fast, while cotton soaks it up and keeps it close.

Mesh curtains, where the heat collects.
Panels down both sides of the pouch. They hold the intimate area away from your inner thighs, so heat and damp have somewhere to go.

Stretches. Grips. Stays put.
The elastic edge moves with your leg and keeps the fabric from creeping up, without digging in.
