Rated 4 out of 5 by from Warmer than a typical t-shirt I wore the shirt twice. It's warmer than a typical t-shirt, and that's why I bought it. It's pretty comfortable, soft, and falls nice. The fit was just a little odd in the back of the neck. The length was an inch or so longer than I expected, making it snug below the waist; but it's just like the photo.
