PeakProof™ 3L Warm Tricot, 70 Denier Plain Weave, 85% Recycled Nylon, 15% Spandex, 198g/m2, 20K/20K Hydrophilic Waterproof/Breathable Membrane with a PFAS-Free DWR Finish and Brushed Tricot Backer


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.
