Compared to the regular Rookie Pad Set, the Rookie PRO knee pads feature thicker EVA foam padding for increased shock absorption, higher quality / firmer elastic straps and an additional EVA foam O-ring in the inside of the pads which wraps around the knee caps, providing a more comfortable and highly protective contact between the pads and the rider’s body. The Rookie PRO knee pads are super affordable, considering the level of protection they offer - ideal choice for progressive young athletes and adults / riders on a budget.
