Just like you, Spyder's Sentinel Jacket craves deep pow and beautiful bluebird days at the resort. Equipped with a waterproof Xt. L laminate and taped critical seams, the Sentinel keeps you dry from surprise powder and heavy snow, and Spyder stuffed the Sentinal with 3M Thinsulate for an abundance of warmth. It also treated the shell with Spylon DWR for additional water shedding protection, and threw in a snap back powder skirt to make sure all the fluff doesn't fly up your back. If the skiing gets too steamy, pop open the core ventilation system and snap off the removable hood for a cooler, lower profile look.
