The upgraded Reactor 2 Spring gives you a full dose of performance technology at an incredible value! This solid suit focuses on using the highest quality materials - resulting in a thin, flexible wetsuit that protects you from sun, stings and abrasions while keeping you warm. Even if the water is 80 degrees, remember that you lose heat 25 times faster in water than in air. A drop in core body temperature means you'll feel more tired and less able to enjoy your hard-earned vacation. Features: Super stretchy 2mm Ultraflex neoprene. Seamless paddle zones. SuperSeal collar: fully adjustable smooth skin neck. Wind resistant smoothskin chest & back. Back zipper with leash for easy on/off. Flatlock stitched for breathable, non-chafing seams. Hidden key pocket. DL Single Seal neck closure. Engineered fit.
