The Dri-FIT Body-Mapping fabric construction of the Nike Men's Tour Dri-FIT Core Body Mapping Polo features strategically-placed ventilation zones to allow air to flow and cool the body where you need it most. This high-performance, microfiber, polyester fabric also wicks moisture 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. Additional features: 100% polyester Short sleeve Three-button placket Solid-knit collar Open-hem sleeves Split hem Swoosh logo at left sleeve
