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 new 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. Over 50% of our product line incorporates preferred materials, which include organic cotton, recycled materials and responsibly-sourced down. We are committed to growing our preferred materials usage to 75% by 2025 and to completely eliminating PFAS from our garments by 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.
