Advantages

Impact protection
Skiing is classified as a high-risk sport, which means that the greatest possible protection is required during skiing. The helmet offers impact protection, which increases the user[s safety on the slopes.
Hardshell construction
The construction combines two layers. One In mould layer with a much harder and thicker outer shell layer. These layers are not closely interconnected and the helmet itself is nevertheless characterised by a higher weight thanks to this construction.
Active ventilation
The active ventilation system allows the airflow to be individually controlled to suit current needs. Thanks to this solution, excess warm air and moisture will be vented to the outside, without being exposed to excessive cooling.
EN 1077 certification
This is a European safety certificate which certifies that the helmet has passed crash and point tests. The first part of the test determines the maximum force that can act on the helmet during a collision, checking absorption through deformation, while the second tests the strength of the shell during point impacts, such as with a ski pole.
Buckle fastening
The chin strap uses a classic buckle fastening. It is easy to use, but fastening and unfastening it can be problematic with winter gloves. It will work well with helmets designed for slightly older children.
Soft ear muffs
Soft ear muffs are a different helmet design with ear muffs that are not overlapped by the helmet shell. They are extremely soft and protect the ears from the cold without interfering with sound reception. They do not, however, provide protection against injuries that may occur in the event of an accident.
EPS inner shell
Under the outer, impact-resistant shell, there is an inner layer of EPS foam. It has a varying density and its main function is to absorb the force of impact during an accident. It provides a good level of safety.
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.
