The quality of this shirt is great. Fabric is very comfortable, and is a great quality shirt. I was excited when OR got some 3x polos in, but they are sized "small" for a 3x. I'm a little over 6'5 and around 300 lbs, and very broad shouldered. The chest is right at 52 inches, which is on the small side for this size range. I've tried to the 2x before, and I think the only difference between the two is that the 3x shirt might be longer (at 6'5, I thought the 2x length was plenty). Unfortunately, I had to return them. Hope this helps my fellow Fat and Talls!
