Very good product. full grain leather. Not synthetic or sanded and finished "leather" with the mall store's brand. Seriously, if you look at almost every strap on the rack, it says 100% leather. 100% leather = shredded scraps held together with glue. Real leather = shredded scraps held together with glue. Buy Top Grain or Full Grain. Anything else will look fine for a month or two and then fail you. PS: measure the waste and add 2 inches. This will take you to the middle hole.
