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 covers the top and sides of the head properly. When your child is riding, always check that the helmet is in place. For maintenance, clean the helmet with a mild soap and water. Don't use harsh chemicals as they can damage the shell and foam. Store the helmet in a cool, dry place when not in use. Also, remember to replace the helmet if it has been in a significant impact or after a few years of use.
