"The Patagonia Grade VII Down Parka is Patagonia's warmest lightweight down piece, built specifically for the cold end of the alpine spectrum. It packs into the top of a pack without claiming the space a heavier insulator would, so it stays on the body when the route demands it. The helmet-compatible hood and six-pocket layout stay functional over a harness and under a shell. What Our Gearhead® Experts Are Saying:""At a belay stance in the dark, this is the jacket I pull on without thinking. The 900-fill down in a Pertex Quantum Pro shell compresses small enough to live in the top of my pack all day."""
