Quick verdict

LiftEvidence editorial assessment

A 4 in wide leather belt with a double-prong buckle, double-row stitching and 12 holes at 1 in intervals, sold in sizes from about 22 to 49 in. It is the most widely owned lifting belt on Amazon.com, and owners consistently describe solid construction, a buckle that holds and support that does not pinch. It is a general-purpose belt rather than a competition one: Dark Iron Fitness does not publish its thickness, and it is more flexible than a 10 mm powerlifting belt — which makes it easier to live with for squats, deadlifts and overhead work, but less rigid at maximal loads.
