This might be picky but they are not very esthetically pleasing to my eye, they appear to have too much hardware, there?s pull strap mechanism spliced in the middle of the lap strap to your buckle.
That is because it is necessary to keep the buckle relatively centered side to side-------so you can not just take up slack from one side to make the belt fit different sized bellys.
All part of the design to distribute the load of the belt, and shoulder harness assembly in case of an impact.
