To use this RVCA rash guard, simply slip it on before you head out for a surf. It's designed to fit snugly but still allow for a full range of motion. Remember, this rash guard provides UVA and UVB protection, so it's great for keeping the sun off your skin. When you're done surfing, rinse it with fresh water to remove any salt or sand. Hang it to dry in a shaded area to maintain its stretch and color. Avoid using harsh detergents when washing it. Just use a mild soap and gently hand - wash. This will help keep the rash guard in good condition for many more surfing adventures.
