The ToughBuilt® Waterproof Knee Pads have a pliable outer shell, which protects your knees when working on rough terrain and, at the same time, prevents scratching of delicate surfaces such as laminate flooring. They are useful for wet and dirty jobs, floor tiling or gardening. Lined with high-density, closed cell foam they provide all-day comfort. The flexible outer accordion construction keeps out debris while also maintaining comfort while walking. A single elastic strap on each pad wraps around the upper calf, avoiding uncomfortable bunching behind the knee. The kneepads are easy to clean after use with water.
