Using this helmet is easy. First, adjust the straps to fit your head size, which ranges from 54 to 58 cm. Make sure the helmet sits comfortably on your head and the integrated fit system keeps it in place. When you're out riding your bike, skateboard, or scooter, it'll protect you and keep you cool with its aerodynamic vents. Remember, this helmet is for kids aged 8 to 14, so make sure it's used by the right age group. To maintain it, simply wipe it with a damp cloth regularly. Avoid using harsh chemicals as they might damage the helmet's design and structure. Keep it in a cool, dry place when not in use.
