Overview
A 4-inch wide, 6mm cowhide leather powerlifting belt (model WPB-RD1-DEU) with a dual-pronged roller buckle and 12 adjustment holes, rated by RDX to support lifts up to 700 lbs.
This is the leather counterpart to a nylon lifting belt, aimed at lifters who want the rigidity that only a thick hide belt provides for max-effort squats and deadlifts. RDX lists it as IPL and USPA approved, which matters if you compete under those federations.
- 6mm genuine cowhide leather construction
- Dual-pronged roller steel buckle, 12 holes
- Rated for lifts up to 700 lbs
- Constant 4-inch width throughout
Who it's for
Suits powerlifters and serious strength athletes who want a stiff belt for heavy singles and competition. Less suited to people who want to put a belt on and off quickly between exercises, since the pronged buckle and holes take more time than a hook-and-loop closure.
Strengths and trade-offs
Drawn from this product's published specifications.
- 6mm cowhide leather for rigid core support
- IPL and USPA approved for competition use
- 12-hole adjustment with reinforced rivets
- Pronged buckle is slower to adjust than hook-and-loop
- Heavier and stiffer than a nylon belt
Performance notes
The 6mm cowhide construction with a suede inner lining is built to maximize core stability and abdominal bracing under heavy load, while the dual-pronged steel buckle locks into one of 12 precision holes for a fixed, repeatable fit.
