New England Patriots Navy Blue Polyester Mesh V-neck Shirt Size Youth M Made by Franklin.  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=39". Back Length=22".  Sleeve Length=7".  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.
