Between the sherpa in the body and the insulated arms, you're as warm as can be. I'd give this five stars, but they hood sits a bit awkwardly since you can't tighten it and it has such a big opening. To solve this, I just wear a light hoodie underneath so I don't have to wear the jacket's hood. Also the jacket runs a bit big, so get your normal size to layer under or size down if you want to wear a jacket over it.
