The Zurich performance top is one of our most breathable items. Contrast inserts at shoulders and on the sides to give the wearer an even more intense athletic look. Topstitching and a relaxed fit help ease your movement and reduce chafing to allow greater comfort. Lightweight 100% microfiber polyester ActivCool fabric dries in minutes and keeps you cool. Our Activcool fabric offers inherent moisture wicking and is treated to inhibit growth of odor causing bacteria.
