I got this months ago with the purpose of taking it to Alaska on our cruise last September but the weather there was not cold enough at that time so I did not bring it and had not used it yet. When It arrived and I tried it on it fitted me very well. As to warmth, I was instantly warm as I was in the comfort of my home. I don't doubt that it will warm me when I use it in a very cold condition with it being made of down. A very good buy for me.
