Descente jacket. Men's size S, but it feels large, possibly due to the outer material, so I've categorized it as M. Please be aware of this. Please refer to the tag information and the actual measurements provided below. Approximately 54cm pit to pit, 65cm back length, and 42cm shoulder width. The inside is not mesh; it's an insulating material. Windbreaker, track jacket, training. I did a lot of shopping and only wore it once last year.
