I ordered a size 38 and I have to wear it in the tightest hole. I usually wear a size 33 pants and I knew the size 34 belt would be too small. I may be going to the nearest shoe shop to have them punch another hole in it if I lose a few pounds.
This was a great upgrade to my Mossy Oak hunting belt. The stiffness and thickness of the leather removes the sag I experienced making it much more comfortable to wear. I can't imagine or would want a belt to be any thicker than this. The buckle is removable if you have Allen wrenches but i don't know what size you would need.
 For the money, there isn't anything else even close to it. You will pay at least $50 for a better belt. If you've been holding out for a good deal on a gun belt, you can't beat the $27 this belt costs.
