Dry.Q Elite shell is waterproof, breathable, windproof, durable and lightweight. Hidden baffle construction preserves waterproofness and durability. Laminated, double external zipper flaps keep water out. Ergonomic draft collar blocks the escape of heated air from inside the bag. The two-piece collar drapes naturally over neck and shoulders creating a soft comfortable seal. Two draw cords can snug down as needed to secure the collar.
