Patagonia's lightweight Down Shirt Full Zip Jacket for Men stuffs inside itself so you can take it on all your adventures. The Down Shirt is a minimalist midlayer for the fall alpine jaunts, and it adds a boost of lightweight warmth for summer backpacking trips in high altitudes, winter ski sessions at the resort, and year round multipitch climbing. Its Traceable Down comes from non live plucked and non force fed geese, and Patagonia had it third party verified, so you can wear it guilt free. To further its green status, Patagonia made the Down Shirt's shell out of a durable polyester ripstop that comes from recycled plastic bottles. Patagonia also added its proprietary DWR finish that lasts significantly longer than standard durable water repellent coatings. The Down Shirt also has two handwarmer pockets and internal drop in pockets for gear, snacks, and valuables.
