Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
Stack Vent Technology
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.
All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The Integrated MIPS® 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.
P.O.V. Camera Mount
The Integrated POV Camera mounting system is stealthy, secure and super easy to operate, allowing you to instantly deploy your POV camera for filming or quickly pop it off and stash it.
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
