The ToughBuilt® Waterproof Knee Pads are a versatile solution for wet and dirty jobs. They have a pliable outer shell which protects the knee on rough terrain while preventing scratches on the most delicate surfaces. Closed cell, high-density foam provides all-day comfort and the flexible accordion construction keeps out debris whilst also maintaining comfort while walking. A single elastic strap on each pad wraps around the upper calf, avoiding painful bunching behind the knee. The knee pads are easily cleaned with water after every job.
