This high-performance, microfiber, polyester fabric wicks sweat away from the body and moves it to the fabric surface, where it evaporates. As a result, Dri-FIT fabric helps you stay dry and comfortable. 4-way stretch fabrication and reinforced flat seam construction combine to provide optimum mobility and superior durability. Self-fabric mock collar, contrast stitching, and print Nike Swoosh at neck. Mesh side panels for breathability and UV protection up to 30 UPF.
