The Cirque, Alta Chutes, Tower 3, the Bowl…iconic Jackson Hole ski runs deserve iconic winter protection. Constructed with PeakProofâ„¢ Dermizax®, a 3-layer polyester fabric that offers exceptional waterproof/breathable performance, the Environ is comfortable, sleek, eye-catching and ready to take on the worst weather the mountains can deliver. For even longer lasting durability without sacrificing its soft hand, we beefed up the face fabric to 150 denier, while a 20 denier tricot backer helps move moisture and provides comfort inside. Features include YKK® waterproof Vislon® and Aquaguard® zippers, pit-zips for ventilation when temps rise, handwarmer pockets, chest and internal stash pockets. A fully adjustable, helmet-compatible hood with laminated brim provide additional protection and a built-in powder skirt keeps you dry on the deepest days.
