Using the Jetblack Comp 2.0 Full - face Helmet is easy. First, make sure to adjust the straps so the helmet fits snugly on your head. Put it on like you would any other helmet, with the front facing forward. When riding, always keep the visor clean for a clear view. As for maintenance, clean the helmet regularly with a mild soap and water solution. Don't use harsh chemicals as they may damage the shell. Store the helmet in a cool, dry place when not in use. And remember, if the helmet has been in a crash, replace it right away for your safety.
