How to use: Simply put the helmet on your head and adjust the straps to fit snugly but comfortably. Make sure the helmet sits level on your head and covers the top part. The chin strap should be tight enough so that the helmet doesn't move around when you shake your head. Attention: Don't wear the helmet if it has been damaged in any way, like cracks or dents. Avoid exposing it to extreme heat or chemicals, as this can weaken the helmet's structure. Maintenance: Clean the helmet regularly with mild soap and water. Use a soft cloth to wipe it down. Let it air - dry completely before storing it. Keep it in a cool, dry place away from direct sunlight when not in use.
