Green Bay Packers Green Polyester shirt Size Youth Medium Made by Under Armor NFL.  Front reads "Packers Performance."   Since not all sizes are created equal, I have included actual garment measurements.  Compare with a shirt you own and it is the next best thing to trying it on.  Chest=36".  Back Length=22.5". Raglan Sleeve Length (from neck)=11".  Please contact seller if you require additional measurements or more info so that you can buy with confidence.  Excellent pre-owned condition.  I can't see any signs of wear at all.
