This is a strong strap with a thick elastic cord that stretches. The buckle is easy to find the right place to tighten and adjust. My husband wears trousers with a waist size of 34-36 and I ordered this belt in a size 38. He says it fits perfectly. He hopes this design will last because the belt looks stylish and is comfortable to wear. The company has included a key ring with a leather thong that you can easily wrap around your belt or clip to your pants belt loop. Good belt, my husband is happy.
