This belt is made from 100% genuine leather with a blended stretch panel along the back, allowing the belt to function as a stretch belt, and therefore pair with all of our existing buckles!

The sizing for our leather belts is slightly different than sizing for our other stretch belts (since they don't stretch quite as far). We have included additional sizes in our offerings to accommodate this!
