Valken Youth Knee Pads are airsoft protective gear that are great for kids that participate in different sports, and other outdoor activities. The X-shaped hard shells allow for better range of motion without hindering mobility, and are made of TPU. The soft cushion pad on the inner side is made of durable nylon, and filled with EVA high density foam for superior shock absorption. They are extremely light and flexible providing excellent shock absorption, and they have two adjustable hook and loop straps for a secure fit. We recommend using our Valken Combat Pants with these knee pads for full lower body protection.
