This jacket is magical. For the price it’s pretty amazing. The only reason this isn’t a 5 star is the zipper is a little on the cheap feel side. Kinda loose feeling while zipping up. I’ve had no issues with it though. That’s being nitpicky. If you don’t have a weird feel for zippers it’s a 5 star review. Very lightweight and very comfortable and warm. I love the sleeve that goes past the cuff so if you are wearing gloves it helps shield them as well to stay warm. Great design and the fit is your regular fit. If you wear a large, get the large. If you want a little room underneath go one size higher. I did that because I like my winter jackets with a little bit of room. Great jacket would highly recommend
