Whether you're headed to work or trudging through the backcountry, the Nano Puff Hoody from Patagonia is a winter essential that should never be left behind. Made with lightweight, hydrophobic Primaloft Gold Insulation Eco, the Nano Puff Hoody continues to trap in heat even when wet and compresses down into it's own chest pocket for extra easy packing. The Nano Puff Hoody also features a weather resistant DWR coating and a durable nylon ripstop construction.
