Proven protection from the elements, the featherweight nylon Patagonia Houdini® Jacket is the go-to running shell for weather-resistant protection. Run, ride, climb—just don’t go without the up-for-anything Houdini® Jacket. It encourages improvisation with its weather-resistant 100% nylon ripstop fabric, which blocks wind and withstands abrasion. The slim fit accommodates a baselayer or a light midlayer; the hood cinches with a single pull and won’t pinch your ears; cording, toggles and cuffs are all trim and lightweight. Half-elastic cuffs seal the wrists, and a drawcord cinches the hem. It packs snugly into its own small, vertically zippered chest pocket, which has a reinforced clip-in loop for attaching to your hydration-pack straps. A DWR (durable water repellent) finish coats the shell and the center-front zipper. With a reflective logo on the left chest and center-back neck.
