I originally bought an XL and returned it for the 2XL. I'm 5'8" and weigh 220 lbs with a beer belly. The 2XL fits great.

The sweater quality is super. It is now my go-to for our cool house or evenings on the patio. It is warmer than my sweatshirts and is very comfortable. I think it looks pretty cool too. In fact I saw GZ wearing a sweater on the TV show The Kitchen and OI could swear it was this exact sweater. I really like it.
