I love this. I bought this because I was looking for a warm zip up sweatshirt to wear at my work. I work early mornings (3am) in a metal building without HVAC. In other words it can get cold. This sweatshirt fits quite well. I wear a 40” regular in a suit jacket so I based my purchase off of that. US Medium fits great. The only downside is that this sweatshirt is so nice, I feel bad using it as a work sweatshirt because clothing usually gets beat up at my job. In summary: It’s warm, it fits great and it looks great. (Even got a few compliments on it)
