I bought this shirt as a Christmas present for my father. He and I both liked the shirt quality, but it is rather short in larger size (he wears a 2-3x normally, so I ordered a 4x to be safe). It's definitely a 4x in width, but not in height for an average to tall man. My dad is 5' 11" and it is barely long enough. So if you are buying for someone who is not any taller or who doesn't like wear their shirt any longer than a couple inches below belt buckle, it would work out great. From my experience in ordering these larger shirts, the bigger sizes don't get any longer in length.
