Absolutely love this jacket, how it fits, and how it looks. It's also surprisingly good quality considering the price. Thick-ish materials (a bit heavier than a standard windbreaker), elastic banding feels like it'll last, sturdy stitching. A lot of other reviews I see are suggesting that you size up, but I think it depends on personal preference. I'm 6'6 and 180 pounds, with a 38 inch chest. I'm pretty thin / lanky. Typically I wear mediums, but I like my garments to be very fitted. After looking at the sizing chart, I decided to size down and go with a small, and I'm glad I did. It fits me perfectly and looks amazing.
