ALPINA ALTONA COMMUTER BIKE HELMET

Thanks to a number of new technologies, the Altona sets new standards when it comes to safety, ventilation, comfort and integration.

The high-performance Koroyd core ensures maximum protection. The stable and extremely lightweight structure consists of a multitude of small tubes that are thermally welded together.

In the event of an impact, they crumple and absorb energy. Due to the stable design, Koroyd also allows for much larger openings in the helmet surface, which guarantee excellent ventilation. Ventilation ducts guide the air inside the helmet along your head.

With the Altona, the ventilation management can also be actively regulated by a sliding upper shell. Whether in the cool morning or in hot rush hour traffic, the ventilation is always optimal.

ADVANCED IMPACT TECHNOLOGY

Koroyd’s welded tubes crumple instantly and consistently on impact, absorbing maximum force in a controlled manner, minimizing energy transferred to your head.

DIRECT AND ANGLED IMPACT PROTECTION

This unique behavior helps to protect your skull and brain from direct and angled impacts which may reduce the risk of suffering a life-changing injury.

ADVANCED BREATHABILITY AND COOLING

Air flows consistently through the open cells so hot air from your head can easily escape, ensuring more efficient cooling in the most intense conditions.

PROTECTION NEVER FELT SO LIGHT

Koroyd features the world’s thinnest walled tubes, resulting in a structure which is 95% air. This reduces weight and enhances comfort without compromising on safety.
