This is a beautiful jacket and seems to me that it would be very warm. I'm unfortunately returning it as it turns out I don't need a parka. I bought it for a vacation, but will just make due with what I have. I live in Florida and don't often have the need for a parka... I'm 5'7" and the jacket is knee length on me. About 130lbs and the Small fit perfect. Very soft lining.
I like the fact that this coat is 700 fill and 85% down and relatively on the less expensive side. I wish it had a more windproof shell. It has two outer side zip pockets, one inside zip (phone) pocket and an open one on the other side. I also wish the coat had a storm flap over the zipper. It fits well - accurate sizing. The other thing I would change is the hood. When I put it on, it falls over my eyes down to my nose, even with the fur off. But I can deal with that since I wont be using the hood frequently. :-)
