If you're going to be outdoors and still need to look professional, you'll love the high-tech benefits of Harriton Men's 4 oz. Polytech Polo Shirt. You'll look good and stay comfortable. The treatment on this 100% polyester fabric adds anti-microbial, anti-static, anti-odor and UPF 50 protection. You'll stay drier as the fabric absorbs, wicks and evaporates more moisture than cotton.
