The StayCool JamTee
Meet the StayCool JamTee: the absurdly soft, wildly comfortable performance tee built for sweating, moving, traveling, lounging, and doing human stuff at a higher level.
Made with our new StayCool fabric, it feels smooth and easy like your favorite broken-in shirt, but performs like a technical workout top. It’s super absorbent, ultra-quick drying, and designed to keep you feeling cool, dry, and comfortable whether you’re crushing a workout, running errands, boarding a flight, or pretending your walk counts as cardio.
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, and dries 68.6% faster.
So yeah, it’s soft. But it’s not just soft. It’s “how is this allowed to be a t-shirt?” soft.
The JamTee is your new go-to for high-performance activity, low-performance lounging, and everything in between.
