A. Comfortable lightweight foam padding - Expanded foam and ethylene-vinyl acetate (EVA) provide relatively soft and thick support for your knees while conforming to your knees. B. Reinforced double stitching - Strong stitching prevents tearing and fraying; the material is elastic and can be used for a long time. C. Ultra-flexible neoprene - The neoprene material means that when you kneel, there won't be any uncomfortable materials digging into your legs, and it provides flexibility in kneeling, standing, or walking positions. D. Non-slip straps - The straps are located above and below the knees to keep the knee pads in place; the relatively wide width and Velcro straps fit most knee sizes. E. Versatile - Suitable for cleaning, mopping, gardening, car repair, housework, sports, cargo sorting, etc. Notes: 1. The set includes 11 pairs of non-slip knee pads. Due to manual measurement, slight errors may occur. Please make sure you don't mind this before placing an order. 2. Please understand that the colors may vary due to different monitors.
