Patagonia, an outdoor clothing brand with an environmental focus, was founded in 1973 by Yvon Chouinard, who since 1964 had been making pitons (metal anchors used in rock climbing) that wouldn't damage rock. While insisting on offering the best quality, the brand has contributed to a sustainable society and natural environment by developing eco-friendly materials and returning 1% of its sales to society. Patagonia has redefined the role of a business and continues to inspire the outdoor industry and the world.
