My body weight tends to range from fat to obese, so I like "infinitely adjustable" straps, but they all tend to curve whether they're synthetic or bonded leather or full-grain leather . which I think could be a feature, but it's always bothered me. This strap doesn't: it usually keeps the desired length, but if it slips, it's easy to tighten even while wearing. The elasticity also helps keep the waist tight. The buckle digs into my stomach a bit, but only when I'm sitting for a long time. Part quality is solid and I expect the two I have will last a very long time. So far it's been the next best thing to braces, which I hate when I wear them.
