This is a full-zip jacket from the official Nike store for the Atlanta Braves baseball team.

This jacket is BRAND NEW, without tags. It is guaranteed to be authentic, unworn and absolutely perfect.

Marked L.

It measures 25 inches armpit to armpit, 36/37 inches from mid-collar to the end of the cuff, and 28 inches from the collar seam to the bottom of the back. (All measurements done across the back with the jacket laid flat). 

Please compare my measurements with a jacket you have that fits you well.  You will NOT be disappointed.
