Fanatics Chicago Bears Mens Golf Polo Shirt Short Sleeve NWT Read

Fanatics Chicago Bears Mens Golf Polo Shirt Short Sleeve NWT Read New with tags. There is a mark on the back that looks like it could be a flaw in the fabric or some kind of stain (pen/marker mark maybe?). I have not washed this item since it is brand new with tags and I haven't removed the tags. See photos for details and measurements
