I typically wear cotton knit pullovers but find that I'm still left with a bit of a chill. I decided to switch to wool after hearing good things about this sweatshirt, and wow what a difference the fabric makes! I love how lofty and airy it is on the inside. It keeps me cozy and warm, to the point where I don't mind going outdoors for brief stints without a coat on to fetch mail! The shoulders are a bit boxy, as others have noted, and I was hoping it might relax a bit once washed, but since wool is good at maintaining its elasticity, it wasn't going to change that much.
Still, it looks good on me and once I got used to the shoulders, the sweatshirt quickly became a wardrobe staple for me and if I didn't have to worry about others noticing, this would be the only thing I wear as a top for the rest of winter!
The only thing that could make this better is if it were available in more colors :)
