Men's Sun Protective Clothing. Clothes can protect your skin against the sun's harmful ultraviolet (UV) rays. But not all clothing is created equal. Choosing fabric with a UPF (Ultraviolet Protection Factor) of 30 or greater will significantly reduce the amount of UV exposure you receive.  The easiest way to test if a fabric can protect your skin is to hold it up to the light. If you can see through it, then UV radiation can penetrate it – and your skin. All of our UPF Clothing has a UPF rating of 30+ or higher.  We carry sun protective clothing from manufacturers such as Columbia, Royal Robbins, Sunday Afternoons, Hook & Tackle and more.
