When it comes to on-the-job safety, you can't afford to skimp. That's why the Prolock Professional Construction Foam Comfort Safety Knee Pads are such an essential piece of equipment. These tough, durable knee pads are constructed of a 1680D polyester blend for superior abrasion resistance, while the custom-molded EVA foam disperses body weight and provides maximum stability. The single neoprene strap helps avoid painful bunching and fits any size leg from 12.5 to 20-inches around. In short, these knee pads are comfortable, convenient, and above all, totally effective at keeping you safe on the job site.
