The Patagonia Men's Houdini Jacket encourages improvisation with its updated 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. The Houdini® has half-elastic cuffs that 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. It's equipped with a reflective logo on the left chest and center-back neck so you can be seen!
