This helmet comes equipped with MIPS (Multi Directional Impact Protection System), the latest innovation in energy management. The MIPS brain protection system is a low friction layer that allows the helmet to slide relative to the head, protecting the wearers head against rotation force caused by angled impacts. Protection against rotational force is especially important for motorcycle riders because when you crash your head usually hits the ground at an angle, creating rotational force that leads to strain on the brain. By stepping outside the boundaries of standard helmet design MIPS is able to offer revolutionary technology you can rely on.
