The Patagonia Nano Puff Hoodie offers total coverage in tough weather conditions. Made from lightweight, 100 percent recycled polyester, the Nano Puff Hoodie is windproof and waterproof with a durable water repellent (DWR) finish. Itrsquos low-bulk, high performing insulation is constructed from 100 percent post consumer recycled polyester that stays warm when wet and locks in heat. The under-the-helmet hoodie design keeps the hood minimalist. The neck-high zipper helps to hold the hood in place while you run, hike or ride. An adjustable drop-hem helps you seal in warmth while a wind-resistant storm flap behind the center zipper keeps warmth in and cold out. Two zippered hand pockets keep your hands warm and your belongings secure. The internal chest pocket also works as a stuff bag so you can fold your Nano Puff Hoodie down and easily pack it away without added bulk.
