Even more open than jet models, demi-jet helmets are unbeatable when it comes to their lightness, ease of use and ventilation. Their strength lies in their smaller size, which means they can even be stored in the limited under-seat compartment of popular scooter models. In terms of aesthetics, the SOLID-COLOR version stands out for its monochrome shell, available in different colours and with a glossy, matt or metallic finish.
