Hardshell
Special helmet shell moulding technology applied to EPS foam. Guarantees high resistance to external impacts and absorbs shocks.
Thermostat Control™
Thermostat Control™ is a ventilation control system used in helmets that allows the user to instantly adjust airflow with a simple and small button located on the outside of the helmet. This technology allows the wearer to fine-tune the level of cooling and ventilation according to individual needs and changing weather conditions.
In Form™ Fit System
The In Form™ Fit System is a helmet fit system that allows for quick and easy size adjustments, even when wearing gloves. An ergonomic dial located at the base of the helmet provides up to 6 cm of adjustment. The system also incorporates a vertical adjustment feature, allowing the helmet to fit better over ski goggles.
Stack Vent Technology
The Stack Vent technology was developed based on research which showed that most of the warm air that causes evaporation escapes through the central upper opening of the goggles. Aligning the Stack Vent in the helmet with the central opening in the goggles helps keep the goggles clean and fog-free, while ensuring full integration of the helmet with the goggles.
