This is a review for the Yellow color, X-Small. For reference, I am 5'7" and 140 lbs with a 36 inch chest measurement and a 28 waist.

This jacket is very comfortable. The inside is soft and fuzzy. The outside is smooth and I think it looks nice. I removed the optional leather strap around the neck and buttons might have been better instead of zippers for the sleeves. The X-Small was snug, but I think the length fit well. My arms do become a bit restricted at the shoulder/chest area, so if you have a similar build and this bothers you, you may want to go a size up. It's obviously not real leather at this price. I feel like it's Asian sizing so the size you get should be determined by your build and how you like your fit. I live in Florida so I can really say how well it holds up in actual cold weather.

Extremely large for size
