The Sentinel is designed for thrill-seekers on steep descents and deep snow. The 3-layer GORE-TEX N70p fabric resists the elements. Durably waterproof, windproof, and breathable, it is combined with a brushed lining for added softness and lightweight insulation. The bib keeps snow out and has a large front pocket for gloves, a hat, or snacks. TouringCuff™ ankles protect against snow infiltration and simplify the use of ski boot hooks, thigh vents keep you cool on climbs, and the integrated RECCO® reflector aids in search and rescue operations.
