Get your selfie – this vest changes colors with your phone's flash on or while you're out in the sun. This USCG approved One Capella vest features a circular construction for extra rib protection. Asymmetrical segmentation contours to your body to flex with you during maneuvers fill more voids than previous models. Designed to be flexible and buoyant, it includes oversized armholes for increased mobility. Smooth skin with two-way stretch neoprene shell. Water-resistant liner increases comfort during wear. Two buckles and 1 zip closure. Style will easily fit longer torsos. Sizes: S(31"-34"), M(34"-37"), L(37"-40"), XL(40"-43"), 2XL(43"-46").
