The best 34 mph ski available. The Connelly V innovative tunnel has 6 V-shaped steps that prove far superior to any other design. These steps grace the edge-to-edge tunnel which reduces drag and helps speed with less wetted surface area. The result is a smooth, quiet riding slalom ski that is freer in turns and fast-reacting. The narrow tail of the V slalom ski sits deeper in the water to create a symmetric turn with less bounce across the wake. CAPT construction with fiberglass wrap, carbon-reinforced design, closed-cell polyurethane resin core, and hand-tuned Acrylam base. Profile Tech top. Viper Fin System with foil. The Sidewinder brings Hinge Tech to the masses with the first and only step-in waterski binding at a value price. Pull the lever down, and step into the binding effortlessly. Pull the lever up, and feel the zero heel lift. Lycra lined heel and toe hold your foot snug and secure. Sidewinder Boot sizes: S(5-7), M(8-9), L(10-11), XL(12-13), 2XL(13-14).
