Being cold is better than being hot. When you're heat panicking, there isn't anything you can do about it, but when you're shivering, all you have to do is zip up the Marmot Quasar Women's Hooded Down Jacket and get moving it's easier than sleeping in on a Sunday morning. The Quasar is loaded up with 850 fill goose down, which has about the best warmth to weight ratio you can find, so it serves up serious warmth without making you feel like you're carrying a quilt on your back. It also packs up small into it's own pocket, so you can bring it along on those iffy weather days. Down's only as good as the fabric keeping it from leaking, so Marmot chose to use Pertex Quantum, a superlight and strong fabric that prevents feathers from sneaking out and fights off brambles, branches, and rock snags. All of this is complemented by Marmot's Angel Wing Movement, which provides full mobility for hiking, climbing, skiing, and whatever else ing, while the adjustable hood, hem, and cuffs snug up to seal your body heat in and the chilly mountain air out.
