features all-new Channel Flex outer fabric throughout (think stretch), and a new hood design. Total performance begins with single-piece front and back panels for absolute flex. New Japanese limestone Nanoprene Lite adds elasticity and heat like no other neoprene, plus it’s not made of oil. Thermo Dry Celliant lining from chest to ankle provides space-age warmth by refracting your body’s heat. To maximize performance, the Comp X has no smooth skin panels, just 100% super stretchy nylon on the exterior. Other awesomeness includes a watertight zipper and newly redesigned chest entry system, and durable, flexy Fusion X tape. SIMA Wetsuit of the Year for 2017, the Comp-X has only begun to evolve the future of surfing.
