Bought this for my husband based on positive reviews and availability of his size.  My husband has a thicker neck (18") and a "barrel chest", but with the bigger neck size everything else was off. The upper arm area was overly billowy and made the shirt look like a wingsuit. The waist was also way too big. The material of the shirt is really nice, but there were threads coming out of the hems already. It looked worn, and not in a good way. If anyone else knows of a better shirt for a guy with an 18" neck size, let me know!
