How to use: Put on the helmet by opening the straps and placing it on your head. Adjust the straps so that the helmet fits snugly but comfortably. The helmet should sit level on your head, covering the top of your forehead. Make sure the chin strap is securely fastened under your chin. Note: Always check the helmet for any signs of damage before each use. If there are cracks, dents, or other visible damage, do not use the helmet and replace it immediately. Do not modify the helmet in any way, as this can affect its safety performance. Maintenance: To keep your helmet clean, use a mild soap and water solution. Gently wipe the helmet with a soft cloth, and then rinse it thoroughly. Let it air dry completely before storing it. Store the helmet in a cool, dry place away from direct sunlight and extreme temperatures.
