Hyperflex COOLMAX EcoMade water tee shirts are an updated version of a traditional Lycra rashguard. Rather than a tight stretch fit, these tops fit and feel like a comfortable tee shirt. They are great for wearing on the beach or in the water. Instead of cotton, these tops are made from CoolMax EcoMade fabric which is made from recycled plastic bottles. EcoMade is quick drying and transports moisture away from your body, keeping you cool and dry. Order the same size as you would normally wear in a tee shirt. 50 UV Shield. Sizes: 4-16.
