Superbelt. Better than leather. Buckle finishes have not worn off in a few years. I have 2, a brown one with brass buckle and black with chrome buckle. Holes never get elongated and it is sweat proof, no sweat stains. Very stiff and supportive. Highly recommended. Website is a bit like a Billly Mays pitch but I have found it all to be true. No affiliation, happy customer.
