Using this helmet is easy. Just put it on your head and adjust the straps to fit snugly. Make sure the helmet sits level on your head and covers your forehead. When riding, always fasten the chin strap securely. As for maintenance, you can clean the helmet with a mild soap and water solution. Avoid using harsh chemicals that could damage the helmet. Check the helmet regularly for any signs of cracks or damage. If you've been in a crash, replace the helmet even if there are no visible signs of damage, as the internal structure might be compromised.
