PARANUS, Bike helmet

One factor that greatly influences comfort when wearing is the ventilation of the helmet. The strategically sensible arrangement of the vents is crucial for optimum ventilation of the interior. The air is directed into the interior, guided around the head and can flow out again at the back. The head is therefore comfortably air-conditioned at all times.

All Alpina helmets manufactured using the inmold process are fitted with a robust ceramic shell. A polycarbonate plate is stretched under intense heat onto the shape of the helmet in the making and pressed onto the Hi-EPS body under high pressure and thermally bonded to it. The Ceramic shell is characterized by several qualities: It is impact- and scratch-resistant, UV-stable and antistatic.

The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene). The material has microscopically small air chambers that absorb the forces acting on the helmet in the event of an impact. Hi-EPS provides optimum protection and at the same time allows for extra-thin helmet wall as well as narrow helmet shapes.

In the inmould production process, the polycarbonate upper shell is thermally bonded to the Hi-EPS inner shell of the helmet body under intense heat and pressure. This creates a large and inseparable connection between the upper and lower shell. Advantage: The helmet is very light and at the same time extremely stable.

The Run System enables all Alpina helmets to adjust to a custom size by using an easy-to-move dial. The Run System Ergo Flex is the lightest, most comfortable adjustment system offered by Alpina. The delicate design clings evenly to the head and thus increases protection. The Run System Ergo Flex can be adjusted using fine increments – there’s no helmet more lightweight, more comfortable or with a more custom fit.
