How does it work? The high-tech polyester pulls moisture from perspiration away from the skin and to the surface of the fabric where it quickly evaporates leaving you cool and dry for your next run. The fiber structure and density of the polyester allows minimal UV to pass through, protecting you from harmful UV rays.
