Using the Loma MIPS bike helmet is easy. First, adjust the straps so the helmet fits snugly on your head. The helmet should sit level on your head, covering the top of your forehead. Make sure the sunglass storage is easily accessible if you plan to use it. When riding, the ventilation system will keep your head cool, so you don't have to worry about overheating. As for maintenance, clean the helmet regularly with mild soap and water. Don't use harsh chemicals as they may damage the helmet's materials. Check the helmet for any signs of damage, like cracks or dents, before each ride. If you notice any damage, it's time to replace the helmet. Also, remember that this helmet complies with the U.S. CPSC Safety Standard for riders aged 5 and older, so make sure it's suitable for the rider's age.
