LS is short for La Sportiva. Tour is short for Alpine Touring. Precut is short for No Extra Work. The LS Tour Precut skins match the La Sportiva alpine touring skis with a 70/30 blend of mohair and nylon. Forgoing the Z-Clip attachments system of the HiGlide skins, the new LS Tours features simple tip brackets and adjustable tail clips. Sportiva also introduces a special weave and factory wax designed for speed. The skins continue to have a waterproof membrane and are impregnated with a water-resistant treatment. The precut skins match the 2.0 line of skis (RST, GT, GTS) and also the Vapor Svelte.
