A poly rash vest is a very useful piece of kit for water sports enthusiasts. Energetic water based activities such as surfing and wake boarding can cause rubbing around key areas of your body including your chest, neck and shoulders. This could be from the friction of the board or your wetsuit as you move around.  Poly rash vests help to prevent chafing and soreness.  Poly rash vests also provide a layer of additional warmth in cooler water conditions and can be worn under wetsuits or over swimming suits. The Alder ‘Spirit’ sleeve poly rash vest offers a protective layer between you and the wetsuit to eliminate rash.
