Extremely warm! It's labeled as size S, but it runs large. You can layer it with a tight jacket. I'm selling it because I have too many similar items, so I'm offering it while it's still in good condition. The hood's fur is detachable. It has many pockets inside and out, so you can go out hands-free! Slight scuffing on the cuffs, please see the images. I will flatten it for packing just before shipping.
