Thin in the shoulders
Both my roommate and I are former swimmers and the XL jacket was too narrow in the shoulders for either one of us. I am a true L/XL for my shoulders and chest, and I could only zip this half way. My roommate, who is usually a M/L got it zipped but it was too tight over her shoulders and across her chest. It is a great jacket (the black/turquoise looks awesome in person), I just wish it wasn't so narrow up top.
