This base layer performance top has you covered. In an updated fit and style, it's designed with proper proportions for Big and Tall guys in a smooth and lightweight in a polyester stretch blend that allows for the freedom to move without restriction. Speedwick technology helps to wick away moisture to keep you feeling cool and dry while built-in performance properties ensure the fabric stays fresher longer and keeps odor at bay. UPF 30 sun protection safeguards you from harmful UV rays so you can stay (and play) outdoors a little longer. Wear it on its own or under your favorite Reebok golf polo when there's a chill in the air.
