Made of tough, genuine leather, the 230LTR Leather Knee Pads provide excellent traction and knee protection from fire, slags and sparks. Leather is abrasion-resistant to maximize longevity for the pads and your knees. Material wraps around the top of the pad to protect the edges from wear and tear. Foam padding made with nitrile rubber (0.5"/12mm thick) maintains its shape over time. Pads protect your knees from injuries and reduces lower back stress. Nonslip, dual straps easily adjust to most knee/leg sizes, and the buckle closures keep the knee pad securely in place all day without restricting circulation. Anti-odor treatment protects the inner fabric so the pads stay fresh. Soft, durable pads are great for workers in construction and flooring/concrete applications. Resistance to heat, fire and abrasion allows excellent welding knee pads as well.
