The Comfort Hinge design adapts to movement and ensures improved comfort, fit, and stability. The abrasion-resistant cap and durable buckles ensure long-lasting use on tough job sites. Supportive gel and NBR foam protect the knees on rough surfaces. The large non-slip hard rubber cap provides traction and still allows workers to move smoothly and safely. Surfaces are not scratched or marked, and the knee pads stay in place thanks to the hinge design, strategically placed straps, and durable locking buckles. The thick elastic straps can be easily adjusted for a custom fit. The knee pads were developed and tested for use by airline baggage handlers, making them some of the most advanced knee pads in the industry.
