The Contour Hybrid Splitboard Mix Skin is a 70% mohair 30% nylon climbing skin. These Contour skins feature a proprietary Hybrid glue technology which is a twin layer adhesion technology. Fancy, I know. This means there is one form of glue that glues the skin glue to the skin. The second glue sticks to your skis. This separation of glue recipes creates a skin that is less sticky to your ski, but has consistent adhesion through a day of touring. A win-win if you will. The Contour Hybrids are also the only to refresh the adhesive. If you hate managing backcountry glue messes, go with the Contour Hybrids.
