Using this bike helmet is easy. Just put it on your head and adjust the straps until it fits comfortably. Make sure it sits level on your head. When you're out cycling, the ventilation system will keep you cool. If you need to take a break and the sun is still strong, you can use the front pass - through channels to store your shades. As for maintenance, you can use a mild soap and water to clean the helmet. Gently wipe it down, then let it air dry. Avoid using harsh chemicals as they might damage the helmet. Also, regularly check the straps and the overall condition of the helmet. If you notice any cracks or significant wear, it's time to replace it.
