When effort is high, the wrong top can trap heat, hold sweat, or become a distraction. The BOUND Signature Short Sleeve was designed to solve that with a featherlight, ultra-breathable fabric that moves freely and dries fast. All-over air holes and minimal seams help regulate heat during fast miles. Built for racing, tempo work, and fast-effort runs, this short sleeve is designed to stay out of your way.
