It is very different from the usual belt, so it has some pros and cons: Pros: - elastic band allows free movement to the limits of the pants , adjustable for sitting, standing, bending over etc - no fumbling with belt when going to the toilet - no adjustment needed when used with similar pants. Length, because the adjustment is not in front of you, where it is easy to reach, and the adjustment mechanism is more complicated - even if you are the same size, the distance between the front belt loops can be adjusted differently for different pants - without a belt The buckle is visible, best used when not visible because shirt will not be tucked in, not suitable for some formal purposes - extra stress on front belt loops and fastener (button, zipper, etc.) is likely to cause more wear and tear than ordinary ones Belt. So it all depends on what is more important to you, pros or cons.
