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.
