Frequently Asked Questions

What is the difference between a lever clasp and a prong buckle?

A prong buckle requires manually threading the belt strap and pressing a prong through a hole — it is adjustable hole-by-hole but takes time to fasten and remove between sets. A lever clasp locks at a single preset position with a simple flip mechanism, allowing you to put the belt on and take it off in seconds without readjusting. For training sessions with multiple heavy sets, the lever clasp provides much faster transitions. The trade-off is that adjusting the tension requires a screwdriver to move the clasp position, rather than simply choosing a different hole.

Is this belt approved for powerlifting competition?

Yes — this belt is approved and recognized by the International Powerlifting League (IPL) and the United States Powerlifting Association (USPA). Before using it in competition, verify the specific approved equipment list for your federation and division, as approved product lists are updated periodically and vary between organizations.

How do I size a lever belt correctly?

Measure around your waist at the navel — this is where the belt typically sits during training. Select the size whose range includes your measurement and verify against the RDX size chart. For lever belts, accurate measurement is particularly important: unlike prong buckle belts, you cannot adjust tension hole-by-hole. The lever should close comfortably with the belt sitting snug against the torso — not so tight that it restricts breathing, but firm enough to feel meaningful compression.

What is Nubuck leather and how do I care for it?

Nubuck is top-grain cattle leather sanded to a soft, velvety surface — more durable than suede with better shape retention under repeated mechanical stress. Wipe down with a dry cloth after each session and allow to air-dry fully. Apply a Nubuck conditioner periodically to maintain suppleness and prevent cracking, particularly around the lever clasp attachment point. Store flat or on a hook — do not fold for storage.
