Our belts are very tough but must be used properly according to the included directions. The operator MUST thread the belt tab properly through the buckle and around the floating bar (Instructor Belt) or between the rings (Frequent Flyer, Ring Belt) before fastening with the Velcro® (see pictures below). The hook-and-loop fastener is only to retain the loose end from flopping around; the buckles are designed to secure the belt. They will quickly lose their stitching and be destroyed if the buckle is improperly used. With proper threading our belts should last for years. Of special importance, the Velcro® securing the end tab has no load-bearing capability on its own and the safety function of the Instructor Belts will be completely undermined if improperly used. We recommend cleaning any lint or particles out of the hook and loop Velcro® once in a while to extend its life and maintain its adhesive abilities.
