Stio Environ Jacket W

Our award-winning signature waterproof/breathable ski shell features recycled nylon and is packed with skier-first details including a powder skirt, pit-zips, a helmet-compatible hood and Aquaguard® zippers.

The Cirque, Alta Chutes, Tower 3, the Bowl…iconic Jackson Hole ski runs deserve iconic winter protection. Constructed with PeakProof™, a 3-layer recycled 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 used a 150 denier face fabric, while a 20 denier tricot backer helps move moisture and provide comfort inside. Features include a forearm RFID pass pocket, YKK® waterproof Vislon® and Aquaguard® zippers, pit-zips for ventilation when internal temps rise, handwarmer pockets, and chest and internal stash pockets. A fully adjustable, helmet-compatible hood with a laminated brim provides additional protection, while the built-in powder skirt keeps you dry on the deepest days.
