The Nomad skin fibers are 70% Mohair and 30% Synthetic Nylon. The natural mohair fibers deliver exceptional glide in any snow condition because they remain soft and flexible at any temperature. The nylon fibers provide extra traction when the skin track gets steep or icy and improved durability over 100% Mohair skins. Nomad skins are PFC-free and are coated with Bluesign-approved EVER DRY 3.0 Anti-glopping treatment to improve performance in wet snow. Jones Nomad PRO Skins are also laminated with RUBBER SAFER SKIN backing. This rubber layer keeps the skin from absorbing water and makes the skins easier to pull apart.
