The Stone Jacket is the perfect eco-friendly jacket for your winter expeditions. It features a Dryplay 20K/15K membrane and a Teflon Ecoelite™ PFC free durable water repellent treatment for maximum waterproofness and breathability. The body mapping construction incorporates our Thermal Dry System that wicks away sweat where you need it most, and a Coremax lining eliminates cold spots. The fully-taped seams, wrists gaiters, and waterproof zippers keep moisture out. For enhanced protection and fit, the hood, cuffs, and powder skirt that attaches to your pants are all adjustable. Choose the right level of warmth all season long based on your outing and the weather.
