This is a great coat for staying warm on a windy icy summit or low activity in a cold environment. You get the nice warm feeling of down in a lightweight synthetic, Very comfortable. Unfortunately, the whole thing is kinda ruined by the use of a tiny flimsy zipper. So small it is hard to get started, even with bare hands, which is not ideal in frigid conditions. OR would have a real winner if they put in a more substantial zipper.
