This heavy-duty belt is made out of 1 1/2 inch wide heavy harness leather. Harness leather is stuffed with waxes and oils in the tanning process. The leather is 13 oz thick. This makes or a great belt to carry a pistol on as it will not roll out and cause the weapon to hang away from your body. There are 9 holes so you can easily adjust the belt to it fit you snugly and go from IWB to OWB easily. The belts have stainless steel buckles. The buckles are attached with Chicago screws so that the buckles are interchangeable.
