How to use: Just put on the helmet like you would with any other bike helmet and adjust the straps to fit your head comfortably. Make sure it sits firmly on your head without being too tight or too loose. Attention: Always check the helmet for any signs of damage before each use. If there are cracks, dents, or other visible damage, stop using it immediately and replace it. Do not expose the helmet to extreme heat or chemicals as this may damage its structure. Maintenance: Clean the helmet regularly with a mild soap and water solution. Use a soft cloth to gently wipe the surface and the padding. Let it air - dry completely before storing it in a cool, dry place.
