I was scared of finding a belt as I currently wear a 54x29 suit pant and most belts will also fit the next size up but I bought a 56 and it was long enough to use two notches instead. Suck to get one, then let it dig with other straps all day. If I lose weight I will be buying more of these pants as my pants are shrinking in size. I don't know about the durability but it lasts a few months, I'm not complaining about the price. Goes great with my work pants.
