The Cat Ultra-Soft Knee Pads - Hard Shell offer the best of both hard shell protection and soft foam to protect your knees during prolonged kneeling. Wrapped in tough polyester the interior EVA foam comfortably cradles the knees in a soft surface while your body weight pushes down on hard surfaces of a job site. The PP hard shell on the outside protects the knees from hard or sharp impacts. Designed to fit the average leg and with the added adjustability of dual elastic straps, these knee pads will fit just about any adult comfortably. The Classic CAT colors are accented with high-visibility red snaps on the straps to help speed up securing the pads to the legs.
