I Love the thickness of this belt. It is study, but not so thick it is cumbersome to get on or to "chunky." That said, the belt sizes DO NOT reflect pants sizes. I wear size 36 pants so i ordered a 36 inch belt. I couldn't even buckle it. I had my buddy try it on he is a 32 inch waist and he made it back to the 3rd hole as a tight fit and the second hole as a comfortable fit. I would suggest ordering a size or two up.
