The K2 Annex 108 Climbing Skins are pre cut for the Annex 108 skis, so you don't have to fuss with razors and keeping dog hair off of the super sticky bottoms of the skins. The Mohair blend skins 30% nylon, 70% Mohair, a silk like fabric or yarn made from the hair of the Angora goat create K2's best gliding skin, with the durability required to last multiple seasons. The Z Clip design provides a secure self centering attachment that reduces weight and allows for quick transition on the ascent. Adjustable tail straps center the skin and sit on top of the ski, which eliminates drag and friction for improved glide and efficiency. These skins are not only technologically sound and functional, they are also ready to ski right out of the box.
