Here's a long sleeve polo that's so unbelievably lightweight and effective in wicking away moisture, it actually beats short sleeves in the comfort category. Our Men's Tropical Weight Long-Sleeve Polo is chock full of sun-smart features. Plus, the polo features our latest technology development called ZnO SUNTECT®. ZnO SUNTECT® embeds millions of tiny particles of zinc oxide — the same ingredient that is used to block UVA & UVB in better sunscreens and to treat mild skin irritations and burns — into every fiber. These ZnO particles cannot wash or wear out. No other men's polo shirt can compare!
