Did you know that clothing is the most effective form of sun protection?  Our rashguards offer the highest rating in sun protection at a UPF of 50+.  Ultraviolet Protection Factor (UPF) indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin. So, a UPF 50 fabric blocks 98 percent of the sun’s rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk significantly.
