An Icon of Road Helmet DesignThe Synthe MIPS II is an icon, updated to be cooler and more comfortable than ever before. The compact design slips through the air with ease yet offers impressive cooling power in a light-yet durable design that's been a rider favourite for years. It's packed with our best features, including the Roc Loc 5 Air fit system with 2-way fit tuning and integrated MIPS (the Multi-directional Impact Protection System), the market-leading brain protection system designed to redirect rotational forces away from the brain and provide more protection in certain impacts.MIPS Brain Protection SystemAll Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
