Additional Information




MIPS is a system used to reduce the rotational forces on the brain in the case of oblique impacts. This is achieved by allowing a controlled rotation of the shell relative to the liner.


Makes it easy to dial in a custom fit in seconds, even with goggles on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability while the vertical turning feature accommodates different goggle and head shapes for a custom fit, free of gaper gap.


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 was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.
