My son plays a minimum of 3 games of basketball a week and has been wearing knee guards from a competitor that costs double the price and honestly doesn't last very long. He's worn the BASE Curved Padded Knee Guards on both legs for a couple of weeks now and says they are brilliant! They don't slip, fit like a glove and give him the protection that he needs as a 10 year old going in hard after the ball. As soon as he put them on for the first time he loved them! They are great value for money!
