Big mountains and deep snow - the Sentinel's made for epic days. Storm protection comes from the N70p 3L GORE-TEX fabric. Durably waterproof, windproof, and breathable, it has a brushed liner to add light insulation and softness. The full bib keeps snow from creeping in and has a large front pocket to stash gloves, beanie, or snacks. The TouringCuff keeps out snow while making buckle management easy, thigh vents dump heat on the uptrack, and an embedded RECCO reflector can aid search and rescue.
