How to use: Put on the helmet by placing it on your head and adjusting the straps to fit snugly under your chin. Adjust the visor to the angle that suits your vision and goggle use. If you want to record your rides, attach your GoPro to the removable mount. Important notes: Always make sure the helmet fits properly. An ill - fitting helmet won't provide the best protection. Avoid exposing the helmet to extreme heat or chemicals as it can damage the shell and the Mips technology. Maintenance: Clean the helmet regularly with mild soap and water. Let it air dry. Check the straps and the shell for any signs of wear and tear after each ride. Replace the helmet if it has been involved in a significant impact.
