StayCool Jambys

Meet the perfect hybrid of your favorite boxers, briefs, basketball shorts, and NASA-level sweat technology.

StayCool Jambys are our high-performance take on the all-in-one house short: super soft, super absorbent, ultra-quick drying, and supremely comfortable for lounging, sweating, stretching, traveling, and aggressively doing nothing.

They’ve still got everything that makes Jambys Jambys: the wear-commando comfort, the perfect not-too-tight-not-too-loose fit, the closed buttons, the stretchy deep pockets, and the “wait, I’m allowed to feel this good at home?” energy. But now they’re made with our new StayCool fabric, designed to keep you feeling cool, dry, and comfortable when life gets a little more active.

And the lab results are kind of ridiculous. Third-party performance testing found that StayCool absorbs moisture 2,360% faster than Nike Dri-FIT, wicks moisture 2,455% better than Nike Dri-FIT, and dries 68.6% faster than Nike Dri-FIT.

So yes, they’re absurdly soft. But they’re also built to perform.

Wear them for workouts, walks, travel days, hot sleepers, house hangs, couch marathons, or that very specific category of “I might exercise later, but I also might order Thai food.”

Materials: StayCool performance fabric.

James ★★★★★

Slept in these on a warm night and woke up completely dry—that moisture-wicking fabric really works. The length is perfect for lounging around without feeling too baggy or restricted.

Edward ★★★★★

The waistband stays put even after hours of gaming on the couch, and the fabric really does feel cooler than my usual cotton shorts.

Olivia Y. ★★★★★

I wore these for a whole weekend of lounging and never once felt that swampy overheated feeling I usually get from regular shorts. The boxer-brief liner means no chafing and no readjusting, which honestly sold me. Weirdly obsessed with how light the fabric feels.
