The Patagonia Women's Houdini® Jacket is a featherweight weather-resistant jacket. The nylon ripstop fabric of this jacket blocks wind and withstands abrasion on multi hour adventures. The slim fit accommodates as a base layer or a light mid layer; the improved hood cinches with a single pull and will not pinch your ears.Half-elastic cuffs seal the wrists and a drawcord cinches the hem. This comfortable jacket disappears as it packs up snugly into its own small, vertically zippered chest pocket, which has a reinforced clip-in loop for attaching to your hydration-pack while out on the hiking trails (pictured in valley flora cobalt blue colorway). What more can you ask for in a jacket?
