The Alpha SV men's Bib is built for severe alpine conditions. This pant is intended for backcountry ice climbing missions but is more than weatherproof enough for trips to big mountain ski resorts. It features a highly durable, waterproof, and breathable 3-layer GORE-TEX® Pro fabric that's reinforced critical high-wear areas. Arc'teryx designed this pant with a high protective back in a regular fitting e3D pattern. The lower legs have a trimmer-cut for more streamlined performance. Ample ventilation is provided by WaterTight side zippers that feature a comfortable backing flap. The bib chest comes with two large bellowed chest pockets for avalanche gear and your other essentials. The lower legs feature a removable internal LegWrap that reduces crampon snags. Keprotec instep guards protect against ski edges and steel crampons.
