No More Holes in Your Race Kit From Safety Pins

Pinning a bib number to an expensive tri suit is one of those small annoyances that adds up — pinholes in gear you paid good money for, and precious seconds in transition fumbling with pins on a table. The RJ-Sport belt solves both problems with elastic cord-and-toggle bib fasteners that hold your number flat against your body without a single pin. The heavy-duty quick-lock buckle snaps the belt on securely, and it’s fully adjustable from roughly 26 to 40 inches with plenty of stretch, so it fits comfortably over a wetsuit or tri kit without digging in.

The six gel loops are the real value-add for longer races — half Ironmans and full-distance events where you need to carry nutrition without stopping at aid stations for everything. Made from 100% polyester and carefully sewn, the belt is light enough that most people forget they’re wearing it once it’s on. It’s built specifically for triathlon, marathon, and cycling events, and it doubles easily as a training belt for anyone who wants quick access to gels on long runs without a bulky vest or pack.
