Compression & Control: Most models include triple adjustable bands or multiple Velcro straps to provide high compression, flatten the abdomen, and define the waistline.
Supportive Design: Many designs feature built-in steel bones (often 3 or 9) to provide lumbar support, improve posture, and prevent the belt from rolling down.
Closure Systems: Products frequently combine a smooth zipper front with external Velcro straps for a secure and adjustable fit.
