Using the Giro Tremor MIPS helmet is easy. First, put the helmet on your head. Then, use the Roc Loc® Sport system to adjust the fit until it's comfortable and secure. You can do this by tightening or loosening the straps. Make sure the helmet sits level on your head and covers your forehead. When riding, always keep the helmet on to protect your head. After each use, check the helmet for any signs of damage, like cracks or loose parts. If you find any, stop using the helmet and replace it. To clean the helmet, use a mild soap and water. Gently wipe it down, then let it air - dry. Don't use harsh chemicals or put it in the washing machine, as this can damage the helmet's structure and the MIPS system.
