A leg-based iteration of Patagonia's hallowed Houdini Jacket, the Houdini Rock Pants pack down so small they basically disappear. Made from an ultra-lightweight full recycled nylon ripstop, it makes for a perfect wind barrier and is a great layer to have to hand for cycling or running on the trails. Minimally-adorned for enhanced packability and reduced weight, the style features a zipped cargo pocket that double as the style's stuff sack and zipped billowed cuffs.
