This is a great jacket from Under Armour.

It is dark blue with a gold stripe. It has a full front zipper.

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

Marked XL.

It measures 27 inches armpit to armpit, 37/38 inches from mid-collar to the end of the cuff, and 30 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.
