All Giro helmets are desgined to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's integrated Mips equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transfered to rider's brain in certain impacts. Hard Shell Construction produces great helmets at a great price. A rugged outer shell is molded and then attatched to the EPS foam liner. For optimal performance of both helmets and googles, Giro products are designed to work together, unsuring a seamless interface between helmet and google for an exceptional fit and depenedable, worry free function. Stack vent technology was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Vertical tuning accomodates different goggles and head shapes for a custom fit free of gaper gap. Giro Neo Mips Helmet Kids
