New England Patriots Navy Blue V-neck Shirt.  Fabric is a polyester mesh.  Made by Franklin.  The size tag just says "S", but the shirt appears to be too small to be an adult Small - so I am calling it in the Youth size range.  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=33". Back Length=19".  Sleeve Length=6.5".  Please contact seller if you require additional measurements or more info so that you can buy with confidence.  Excellent pre-owned condition.  The only very minor issue to report is the inside manufacturer's tag is faded.  Still readable and could be cut off entirely if this bothers you.
