The advantage here is fact that one of the belt does not have to cut back if you lose weight.
As with a bag, you can easily vary the length of the belt.
Unfortunately, the buckle is not fixedly attached to the belt.
But if you realize how the part is clamped belt, he no longer slip out.
The clip for the longitudinal adjustment clamps sometimes, because it is a little too wide to fit through the belt loops right away.
In my vast army pants are the belt loops very generous, in tight jeans but this is potentially a problem.
Conclusion: if you can live with the small toggle, receives an original belt.
