Patagonia was founded on a reverence for tools built to perform and last—products that you could depend on for your life and that derive beauty from their absolute suitability to task. It began with a young California climber-turned-blacksmith hammering steel into slim, elegant pitons that he and his friends used to put up historical ascents. Today, we make clothes instead of climbing hardware, but our approach to creating anything remains as direct as an anvil strike—and more opposed to waste than ever. In this spirit, we’ll be publishing these guides less often, so we hope you’ll hold onto this one and refer to it to find exactly what you need.
