Alpina - Rocky
The equipment list of the Rocky is long - and thoughtful. The Alpina children's helmet is for kids who want to be safe in any terrain. On-road or off-road: the Rocky is versatile. The low weight is due to the Inmold production in which the upper shell is thermally connected to the Hi-EPS. This results in a firm surface connection, which is responsible for a very stable construction. The Rocky can be adapted to the head shape via the Run System Classic - a plus for comfort. The same applies to the removable and washable antibacterial inner cushion. The rear and temples are lowered for maximum safety. The result is an even larger head cover and even more protection. Fly screens keep insects away from the head, the shield guarantees optimum protection in the field of vision.
Run System CLASSIC SLIDE
The Run System allows the size of all Alpina helmets to be individually adjusted using a smooth-running rotating wheel. The Run System Classic scores with its price/performance ratio. It is a simple and robust adjustment wheel that holds the helmet securely and uncomplicatedly where it belongs: on the head.
A helmet can only provide the best possible protection if it remains in the optimum position in the event of an impact. The adjustment and fixation of the two straps under the ear plays a decisive role. The Y-Clip system guarantees millimetre-precise adjustment - in a matter of seconds.
Proven hundreds of thousands of times and used on all Alpina helmets: the belt buckle with the red push button and multi-stage automatic snap-in mechanism. Ergomatic can be operated with one hand - you can loosen the strap uphill, tighten it downhill - and in the event of a fall it is not possible for the locking mechanism to open automatically.
One factor that strongly influences the wearing comfort is the ventilation of the helmet. The strategically sensible arrangement of the ventilation openings is decisive for optimum ventilation of the interior. The air is directed into the interior, directed along the head and can then flow out again at the rear. The head is therefore always pleasantly air-conditioned.
The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene). The material has microscopically small air chambers which absorb the forces acting on the helmet in the event of an impact. Hi-EPS provides optimum protection and at the same time enables extra-thin wall thicknesses and narrow helmet shapes.
In the Inmold production process, the polycarbonate helmet shell is thermally bonded to the Hi-EPS inner shell of the helmet body under great heat and pressure. This creates a large-area and inseparable connection between the upper and lower shell. Advantage: The helmet is very light and at the same time extremely stable.
All Alpina helmets manufactured using the Inmold process receive a robust Ceramic Shell. A polycarbonate plate is stretched under high heat onto the shape of the later helmet and pressed under high pressure onto the Hi-EPS body and thermally connected to it. The Ceramic Shell is characterized by several qualities: It is break- and scratch-resistant, UV-stable and antistatic.
