The Kuny's KUNKP-367 Airflow Layered Gel Knee Pads have a perforated side panel designed with breathable mesh fabric and perforated foam to better ventilate the knee pad and reduce heat build up. The Stabili-cap™ design provides a solid kneeling base and also allows for easier forward movement, effectively increasing the range of movement. The layered Gel, high-density closed cell foam and Neoprene padding offers superior all day comfort. For a comfortable fit, the knee pads have elastic straps with hook and loop closures to provide the right fit.
