Using this helmet is super easy. First, put it on your head and adjust the straps so it fits snugly. To switch between full - face and open - face modes, just use the magnetic chinbar release. It's a quick and simple process. When riding, make sure the helmet is firmly in place to ensure your safety. As for maintenance, clean it regularly with a mild soap and water. Don't use harsh chemicals as they can damage the helmet. Store it in a cool, dry place away from direct sunlight when not in use. And always check for any signs of damage before each ride. If you notice any cracks or significant wear, it's time to replace the helmet.
