After months of living and working with the local yak herders and nomads of the Himalayas and Tibetan Plateau, Stefan Warnaar set out to make better outdoor products—ones that would encourage adventure and stand up to the world’s most beautiful, extreme environments. Soon, Peak to Plateau was born, and ever since has been producing performance garments using yak fiber. Dedicated to environmental and social sustainability, the company purchases ethically sourced yak fiber from cooperatives on the Tibetan Plateau to ensure herders receive the fair income they rely on. The rest is done in house: the fiber spun into a superfine yarn, knit into a unique fabric, and crafted into the final product.
