Laidback yet ready to perform, this camp shirt from Columbia is crafted from a lightweight, breathable polyester stretch blend. Omni-Shade™ UPF 40 technology safeguards against skin damage using tight fabric construction and modified fibers to block UVA/UVB rays so you stay protected in the sun. Omni-Wick™ technology keeps you dry and cool by pulling moisture to the fabric’s surface to evaporate, delivering fast-drying, next-to skin comfort in the heat. The mesh back vent design helps keep you cool and comfortable. Designed with precise proportions and an ideal fit for Big and Tall guys, it allows for the freedom to move without restriction and is even equipped with a patch inside the bottom placket to clean your sunglasses and keep them smudge free.
