I was looking to get away from "genuine leather" as that is the poorest quality material. I am impressed with the leather and belt buckle. I am not sure on the longevity of the plastic catch that the buckle clicks into but that will take years of use. I'd like to see a metal option in the future if possible.
As to fit, there is a huge difference in comfort right off the start as my old belt I was in between the notches. Too loose my pants felt like they were going to fall down and too tight my back would act up. If you have lower back issues and need a belt I'd recommend trying one of these out. I use it for work so I have a radio, knife pouch, keys and a phone attached, so there is more than a normal amount of weight being applied.
