The Gel Hard Cap Knee Pads feature a hard cap and are ideal for applications with hard surfaces like carpet, hard wood, sub floor, concrete, and general construction. Mesh, moisture-wicking lining and neoprene/elastic straps give extra flexibility and support. These hard cap knee pads are ideal for swiveling or sliding and are designed with a 2 strap system for additional comfort. The strap system is comprised of a neoprene bottom strap that tightens firmly for support, and an elastic top strap that holds the pad in place without causing discomfort. Both straps are adjustable and attach with a hook and loop closure.
