The Zoot Men's Performance Tri Team Tank Top keeps you comfortably dry and protected from the sun's harsh rays, as backed by its UPF 50 rating. Designed with an Italian sourced blend of polyester and spandex, this jersey actively wicks moisture off your skin where it can readily evaporate for a cool, pleasantly dry feel. Plus, you'll find its ample stretch promotes freedom of motion when you're swimming, cycling, and running. The 10 inch Cam Lock zipper ventilates your core when you're riding and running under the hot summer sun and features a soft finish binding. Further preventing irritation, Zoot's Seamlink construction lowers the stitching profile for a smooth, chafe free feel. Other functional features include three rear pockets for storage of nutritional supplements, as well as a dropped rear hem for extra coverage on your bike.
