How to use: Put on the helmet and adjust the Ergo Fit system with one hand to get a comfortable fit. Make sure it sits firmly on your head. When out in the sun or rain, use the visor to block glare or water. Attention: Don't use the helmet if it's damaged. Avoid exposing it to extreme temperatures or harsh chemicals. Maintenance: Clean the helmet regularly with a mild soap and water. Dry it thoroughly before storing it in a cool, dry place.
