Ski helmet Giro Ratio matte titanium (GR-7172884)

The Giro Ratio matte titanium ski helmet provides a high level of protection and comfort for all mountain riding, combining a robust Hard Shell construction with an advanced ventilation system. Equipped with active adjustment solutions, it allows for precise fitting to the shape of the head and maintains optimal temperature regardless of the intensity of exertion.

Ventilation and fitting technologies

The Stack Vent Technology system directs warm air from the goggles directly through the helmet, reducing fogging and increasing comfort while riding. The Thermostat Control™ technology allows for precise control of the ventilation level, enabling airflow adjustment to current weather conditions. The In Form™ Fit System offers quick and easy circumference adjustment, ensuring stable and secure helmet positioning throughout the day.

Durable materials and Hard Shell construction

The shell is made from synthetic ABS polymer and PC polycarbonate, providing high impact resistance and product durability. The inner EPS polystyrene liner effectively absorbs energy during potential falls, enhancing user safety. The ergonomic shape and buckle closure facilitate quick wearing and removal of the helmet, even in winter conditions.

Certification and user comfort

The Giro Ratio helmet meets the stringent CE-EN1077 safety standards, confirming its reliability during skiing activities. The Soft ear pads protect the ears from the cold and improve wearing comfort, especially during long days on the slopes. The all mountain construction makes this model suitable for varied terrain conditions, whether during leisurely rides or challenging descents.

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.
