The Millet Pierra Ment XCS Pant is a ski touring pant made from XCS 200 polyamide, a four-way stretch fabric with a DWR water repellent finish that protects against the elements. Thinner areas behind the knees promote moisture wicking, and reinforcements at the ankles add durability where boots and edges rub. What Our Gearhead(R) Experts Are Saying:"On the skin track I unzip the side vents as soon as I warm up, and the mesh lets the heat out without me stopping to shed a layer. At the transition I reach the rear boot buckles through the ankle zips, so I switch from climb to ski mode with the pants still on."
