Packed with 850-fill power down, it has the ability to trap body heat at an exceptionally light weight while remaining packable enough for even the most space-conscious backcountry goers. When days stay cold, the lack of bulky insulation makes this a perfect piece for trapping some quick extra warmth without pulling that shell out of your pack.
