The High Speed Gear Sure-Grip Padded Belt is designed to provide the comfortable, no-slip stability necessary for reducing back strain and general discomfort so frequently caused by loose-fitting, drooping and weighted-down belts. Featuring a brand-new modular system, the Sure-Grip has a slim profile that is just 0.75 inches thick and only 4.25" tall. With three conveniently-positioned access ports, the Sure-Grip allows you to seamlessly attach sub loads to the belt's interior, while the belt's four suspender attachments allow for easy expansion.
