Minimalized to perfection, Patagonia's Down Shirt exemplifies the less-is-more philosophy - 100% recycled polyester shell and liner, 600-fill-power 100% Traceable Down (down that can be traced back to birds that were never force-fed, never live-plucked), and essential pockets. That’s it. Sure, there’s jumping jacks, the hot water bottle against the belly trick, and the time-honored partner spoon. But when you need a touch more warmth, Patagonia's Down Shirt makes life easier. Its minimalist, pared-down design traps your heat with 600-fill-power 100% Traceable Down inside a lightweight, windproof 100% recycled polyester shell with a DWR (durable water repellent) finish. The center-front zipper has an internal storm flap and chin guard, and the construction of the two external handwarmer pockets (set into the forward side seams) creates two internal drop-in pockets. Jacket stuffs into either outside pocket.
