A Rash vest, AKA rash guard or rashie, is a shirt which provides protection from getting rash caused by rough wax on a surfboard. They also provide excellent protection from UV sunburn and rapid impact with waves. Rash vests can be worn under a wetsuit to prevent wetsuit rash or by themselves in hot weather. They come in short sleeve, long sleeve and turtleneck styles. Turtlenecks are designed to prevent neck rash from wetsuits. We recommend all parents to protect their young kids with a rash vest while on summer holiday. Whether at the beach, swimming or snorkelling.
