The Castelli Men's Body Paint 2 Tri Top effortlessly transitions from swim to bike to run stages without leaving you a sopping mess. Its ultralight, stretchy Velocity fabric dries quickly once you leave the water for maximum comfort. The top also reflects scalding hot UV rays with its white colored back panel. Smooth flatlock seams won't chafe or irritate sensitive skin. Additionally, you'll find a half length locking zipper for adjustable ventilation, as well as two rear pockets for stashing nutrient supplements and small accessories.
