Laidback yet ready to perform, this fishing sport shirt from Columbia is crafted from lightweight, sweat-wicking fabric with built-in sun protection for lasting comfort on or off the water. Omni-Shade™ UPF 40 safe guards against skin damage using tight fabric construction and modified fibers to block UVA/UVB rays, so you stay protected in the sun while Omni-Wick™ 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.
