Using your MET Rivale MIPS road helmet is easy. First, adjust the straps so they fit snugly under your chin. Make sure the helmet sits level on your head, not tilted forward or backward. When riding, always wear the helmet to keep yourself safe. As for maintenance, use a mild soap and water to clean the helmet regularly. Avoid using harsh chemicals as they can damage the helmet. Store it in a cool, dry place away from direct sunlight. If the helmet has been in a crash, replace it immediately as its protective capabilities may be compromised.
