Built to tackle all types of snow, terrain, and ability levels, the Dynafit Seven Summits Ski is a versatile, all mountain backcountry bomber. Yeah, it can tear up the powder, crud, and iced over crust, but it has to get there first, so it's a good thing you have the Dynafit Seven Summit Speedskin. The Speedskin gives you easy gliding and easy to use capabilities that cut down on the frustration of difficult to use skins. Careful material selection and Dynafit's Anti Stick capability allow for easy gliding, ultimate Snow Leopard Grip, and minimized snow buildup. The Speedskin's three layer construction places a waterproof membrane between the fur and the support material, which makes for much better results than typical two layer skin construction. The easy to use patented clamp system is lightweight, keeps out snow, and the rubber clamps are easy to replace, so you won't have to throw out a whole set of skins if you lose a clamp.
