The Harbinger lifting belts are available in numerous sizes, which makes them an excellent buy for lifters. You can find them in multiple sizes, which range from Small to Extra Large. However, the standard sizes only stop at XL and if you have a larger waist, you might need something slightly bigger. Keep in mind that it is possible to directly contact the manufacturer and order a custom belt of a bigger size. However, this would inevitably cost more and it might take slightly longer for the belt to be delivered.
