Golden State Warriors Gold Shirt Size Youth L (12-14) NBA.  100% Cotton.  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".  Sleeve Length=7.5".  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.
