Dynafit designs their climbing skins with the help of the upski masters, Pomoca specifically for individual skis. For the Sphinx and Meteorite skins they utilized a 3 layer construction comprised of a waterproof membrane in the middle to ensure your glue stays dry and your skin stays on your ski. The grip and glide material is a complex blend of mohair and synthetic materials. This allows the skin to wick away water and provide the best balance of grip and glide. Elastic rubber tip attachment makes stripping skins simple to help you keep transitions quick and easy and metal tail attachments ensure skins stay on in all conditions. All the speedskins are laser cut to each Dynafit ski so there is no need for the do it yourself garage slash jobs. The only thing you will be doing is racing your friends to the top.
