With a revolutionary combination of hard-shell materials and soft foam construction, Vertx Knee Pads provide unbeatable defense without sacrificing comfort. Featuring cutting-edge G-Form SmartFlex™? technology, these knee pad inserts offer a contoured fit with waterproof padding to keep your knees protected in any situation. But what truly sets Vertx Knee Pads apart is their ability to adapt to impact. When at rest, the molecules repel each other, keeping the pads soft and flexible. However, upon impact, they instantly bind together, effectively dissipating energy to minimize any potential harm.
