Aptly named for its ability to pack away into the smallest of spaces, the Patagonia Women's Houdini Vest delivers lightweight, easy stashing protection from the elements. Weighing a scant 2. 1 ounces and able to pack into a micro sized stuff sack, this wind and water resistant shell is ideally suited for minimalist backcountry missions where every ounce and cubic inch matters. It conveniently stows into the zippered chest pocket, which sports a reinforced carabiner clip for attaching to your favorite pack. Although it has a slim fit, it still offers enough room for wearing over your favorite base and midlayers.
