Integrated MIPS Brain Protection System All Giro helmets are designed 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 transferred to rider's brain in certain impacts. Hard Shell Construction Hard Shell Construction produces great helmets at a great price. A rugged outer shell is molded and then attached to the EPS foam liner. Seamless Compatability For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function. Stack Vent Technology Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.
