This weather-resistant little wonder has been on Patagonia's "list of essentials" for nearly a decade. Exceptionally minimal, the Patagonia Women's Houdini Jacket can be stuffed and put into a running short pocket, clipped to a harness, or become a permanent fixture in a pack or carry-on. 100% nylon ripstop fabric blocks wind and a DWR (durable water repellent) coating protects against light precipitation. Its slim fit accommodates baselayers and light midlayers. The Houdini® is the emergency layer you don’t know is there, until it’s not.
