Black StayCool Jambys

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.”
