Children's helmets have different safety issues than adult helmets. This is why we took care to create a helmet for children that has no internal contact points with the soft tissues of the growing child's head. Met Genio helmets are shaped to let kids stand up straight while sitting on the bike saddle. The built-in insect netting on the Met Genio keeps insects and other small items out of the helmet, where they belong. The helmet is equipped with an adjustment knob to adjust the helmet to kid's head. There are ventilation holes in the helmet shell and a rear light.
