It is made to IPF spec from the latest Technical Rule Book.

Made to the Maximum Sizes of Most Powerlifting Federations. This belt comes with a premium bespoke stainless steel lever buckle as standard. The benefit of a lever is that you can tighten the belt to its maximum tightness and release with the minimum of effort making it very quick, easy and safe to use. The stainless steel lever buckle has our signature Cerberus logo laser etched into it and is our exclusive design. This is not a generic cheap lever buckle. Stainless steel is one of the most durable materials on the market and will last you forever! To find your size measure around your waist where you will wear the belt. Subtract 1" (2.5cm) from this and use the guide above. Correct sizing is very important, don't simply select your trouser size as you will be wearing your belt well above your hips.
