Made with 1680D nylon shell and 420D nylon rubber, the 450 Soft Cap Gel Knee Pads with Hinged Straps are built to last for the toughest jobs. Pads protect your knees from scrapes, bruises and minor injuries while working. Hinged straps move with your natural body movements when walking, crawling and kneeling. Long cap maximizes protection and enhances stability to prevent wobbliness on knees. Abrasion-resistant cap avoids scuffs and scratches without damaging other surfaces either. Pads will not slide down or move around thanks to thick, elastic straps. Gel and EVA foam cushion pads provide comfortable, all-day support. Hook-and-loop closures supply an easy way to adjust straps to your comfort level without coming loose. Top strap with locked buckle adds extra security to avoid readjusting pad. Knee pads are tested and approved by some of the most demanding knee protection users, airline baggage handlers. They are also perfect for jobs in construction, HVAC, tiling and more.
