Cassiar Pant

From groomer days to lift-served powder turns, the Arc'teryx Men's Cassiar Pants will do it all. The best of both worlds, this pant is constructed with a protective 3-layer Gore-Tex membrane that shields you from wind and water and a supple 4-way stretch fabric that enables you to move without restraint. A brushed flannel backer adds insulation and comfort when skiing. Internal adjusters leave the waistline clean and add to the pant's streamlined look while giving you a secure fit. Mesh-lined PowderGuard vents let you dump heat on warm days or after a long run. PowderCuffs keep snow from sneaking into your boots, while Keprotec insteps guard your hems against abrasion from sharp ski edges or boots.
