The Savant MIPS is an amazing fit for riders who enjoy great routes as much as a swift pace. The Slim shape combines impressive ventilation thanks to 25 Wind Tunnel vents and the comfortable convenience of the adjustable Roc Loc 5 fit and stability system. And with MIPS technology the Savant MIPS offers an added measure of protection in certain impacts. All 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.
