The Stone jacket includes our brand-new bio-sourced hard shell made from repurposed sugarcane waste that is converted into bio-based polyester. It also features a 20K/20K membrane with a Teflon EcoElite™ PFC-free durable water repellent treatment for unsurpassed waterproof/breathable performance. 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, wrist gaiters, and waterproof YKK®zippers keep moisture out. For enhanced protection and fit, the hood, cuffs, and powder skirt that attaches to your pants are all adjustable. Last but not least, this color-block jacket features several pockets so that you can carry any small essentials.
