SUPreme™ UV Shield™ water tee shirts are an updated version of a traditional Spandex rash guard. Rather than a tight stretch fit, these tops fit and feel like a comfortable tee shirt. The 50+ UV Shield™ helps protect you from sun exposure when spending long hours on the water. They are great for wearing on the board, beach or in water. Instead of cotton, these tops are made from a wicking synthetic fabric which is made from recycled plastic bottles. Water shirts dry quickly and transport moisture away from your body, keeping you cool and dry even on hot and humid days.
