The Nash is our all-time favorite running and biking tee. Why? In part because it’s got Polygiene, a treatment that prevents odor-causing bacteria at the source—so you can skip a laundry load and still smell fresh. With a modern, lightweight technical fabric, the short-sleeved Nash is about maximal ease and minimal fuss. The key is super soft and stretchy fabric that wicks sweat, dries quickly, zaps odors, and wears like your favorite band T-shirt from high school. It’s designed to keep you comfortable and dry when you’re in motion, whether mountain biking, trail running, or throwing horseshoes in the backyard.
