When this jacket first came in the mail, I was a little worried. It felt way, way thinner than my other ski jackets, and I was concerned that it wasn't going to keep me warm while sitting on the lifts. This wound up being a non-issue, as it kept me dry and warm over the course of several long days skiing at Whistler.I ordered a medium, and found that it fit the way I expected it to. There was still room for me to wear a hoodie underneath, if I wanted to (which I didn't - seriously, this is one very cozy jacket.) Overall, an excellent purchase.
This coat is very soft and the pattern is fabulous, although it does run a size smaller. I ordered an XL for my sister so she would have room to layer underneath, and it is way smaller than a normal XL. Will probably have to exchange for something else. But other than that, we loved everything else about the coat!
