The Mineral Jacket combines ethnic style and technologies. It features a DRYPLAY 10K/10K membrane for functional waterproof-breathability, a Teflon Ecoelite™ PFC-free durable water repellent treatment, a Thermal Dry System liner to wick away sweat where you need it most, and 80-g insulation to stay warm. When the sun is blazing, just open the pit zips for ventilation. Critically-taped seams keep moisture out. For enhanced protection and fit, the cuffs with wrist gaiters, and powder skirt that attaches to your pants are all adjustable.
