Using the Giro Scamp II Kids Helmet is easy. First, place the helmet on your child's head. Then, use the Roc Loc® Junior fit system to adjust it until it fits snugly but comfortably. Make sure it's level on the head and covers the forehead. When your child is riding, always check that the helmet is securely in place. For maintenance, use a mild soap and water to clean the helmet's exterior. Avoid using harsh chemicals as they may damage the polycarbonate shell and EPS foam. Store the helmet in a cool, dry place away from direct sunlight. Replace the helmet if it has been involved in a crash or shows signs of significant wear and tear.
