Soft and thick leather; The buckle is strong and attractive. The buckle is interchangeable and what I love about this belt is that the loop that holds the buckle is attached with torx head screws rather than snaps. They also have excellent customer service. I ordered the wrong size because I didn't follow the instructions correctly and it should have measured the belt you're wearing. So the first belt was too small and I put it on the way back. I immediately received a QR code via email, took it to UPS and sent it back for free. The only thing I paid for was a return envelope which I wrote off as a fine for not reading the instructions. Within hours my Revain account was refunded in full and I ordered the correct size. I am very happy with this purchase.
