    In-Mold Shell

    Fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner, allowing for better ventilation systems compared to traditional designs.

    EPS Liner

    Expanded polystyrene (EPS) coats the inside of the helmet shell to absorb energy by compressing in the event of impact, reducing the risk of head injury.


    The multi-directional impact protection system. A low-friction membrane absorbs rotational energy from oblique impact, reducing violent forces on the brain and associated injury.

    Fit & Comfort Technology

    Thermostat Control

    Allows you to custom tune airflow instantly with a simple, low profile slider on the outside of the helmet. No other system is faster or easier to adjust.

    Stack Vent

    Ventilation channels in the brim of the helmet which allow for fog-causing air to be efficiently exhausted from vents in the top of your goggles.

    In Form Fit System

    Makes it easy to dial in a custom fit in seconds, even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability.

    XT2 Anti-Microbial Padding

    Pure silver is woven in to the XT2 helmet padding. Its anti-microbial properties will last the lifespan of the helmet, helping to keep it feeling and smelling fresh.
