Using the Bell Sanction helmet is easy. Just put it on your head and adjust the straps to fit snugly under your chin. Make sure it sits level on your head for the best protection. When you're riding, always fasten the straps properly. As for maintenance, use a mild soap and water to clean the helmet regularly. Avoid using harsh chemicals as they can damage the helmet's material. Store it in a cool, dry place away from direct sunlight when not in use. And remember, if the helmet has been in a significant impact, it's time to replace it.
