Quick verdict

LiftEvidence editorial assessment

A 10 mm, 4 in leather prong belt marketed as IPF-approved — the format most powerlifters train and compete in. With about 2,500 Amazon ratings it has a far larger owner record than most 10 mm belts on the platform. Owners describe it as sturdy, supportive and comfortable without digging into the ribs; the trade-offs are the ones every thick prong belt has: it is stiff, takes time to break in, and is hard to get on and off between sets. Federation approval is the seller's claim — check your federation's current approved list before a meet.
