Our all-purpose outdoor pant, the Keystone is ready for trail days, powder runs, and backcountry adventure. In wet weather, the Keystone uses HydroBlock Sport 10k/10k waterproof/breathable fabric and Skier Critical seam sealing to keep you dry. Full-Motion articulation provides mobility, and zipper handwarmer pockets offer just-right storage without bulk. To keep the Keystone Pant in rotation for years to come, reinforced construction adds mountain-ready durability.
