This is the first down jacket I've owned and I'd give it 5 stars if I were only wearing it to run around town in, it's very nicely fitted so you don't feel and look like a marshmallow. It's been warm enough for Colorado winters and as far as being functional on the mountain I'd suggest a windstopper fleece underneath for very windy/cold days because you can actually feel it if it's a strong wind blowing through the zipper where there is a lack of down. Also noticed that it was nice and waterproof when I got it but I need to re-waterproof it after about 10 wearings, not a big deal.
