Fresh coffee is on the breakfast table, and the morning program is playing on the radio. It's 8 AM, and the city is waking up. It's slowly time to head to the office - with your Altona. Visor down, into the hustle and bustle. The asphalt rushes by beneath your bike. You flow with the traffic. No stress, no worries, with the best possible protection on your head. Altona means "all too close." The commuter helmet from Alpina brings your destinations closer. All your destinations. Thanks to a variety of technologies, the Altona sets standards in safety, ventilation, comfort, and integration. The high-performance material Koroyd ensures maximum protection. Its stable and extremely lightweight honeycomb structure consists of numerous small tubes that are thermally bonded together. Upon impact, they deform over a large area and absorb energy. The stable construction also allows for significantly enlarged openings in the helmet's surface, providing excellent ventilation. Ventilation channels guide the air along the inside of the helmet. With the Altona, climate management can additionally be actively regulated via a movable top shell. Whether on a cool morning or in the hot evening rush hour - ventilation is always optimal.
