Rip Curl's Dawn Patrol line might be priced cheap, but there's nothing budget about the quality of these suits, especially this Short Sleeve Chest Zip Spring Suit. They're constructed of E3 neoprene, which is a lighter, warmer, and more flexible super stretch neoprene material. Seamless underarms provide the ultimate in comfort and fit and unrestricted flexibility. And for quick access there is a stash pocket with key loop on the chest zipper.
