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.

In our outdoor world, not all shell fabrics rate the same, which is why we decided to set a Stio® standard for mountain-rated protection you can trust when rough weather descends. Our PeakProof™ rating ensures a Teton-tested level of waterproof technology and breathable comfort for elevated action in mountain environments.
As caretakers of the mountain life, we recognize our responsibility to support organizations and people who share our vision to drive positive change for people and the planet. We’re proud to partner with some tremendous organizations in their missions to responsibly advance outdoor recreation and protect our wild surroundings.
We are committed to building garments that are durable, timeless and continue to perform season after season. After years of research, testing and product development, in 2024 we completely removed PFAS from all of our newly developed products. We remain committed to growing our Preferred Materials usage, which includes organic cotton, recycled materials and responsibly-sourced down and wool, to 75% by the end of 2025.
Our apparel is built to last. As a part of our efforts to reduce waste and keep more gear in the mountains where it belongs, our home-grown gear renewal program allows previously-used items to be traded in, cleaned, repaired and circulated back into use.
