ROOTAGE 2 MIPS, 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.

Carbon Tec provides the best possible protection. The high-performance carbon material is used in the inmold process. The integrated carbon plates in the outer shell make the helmet more robust. Forces acting on the helmet at certain points are absorbed by the carbon fibres, distributed over a larger area and thus mitigated.

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.

Edge Protect is an additional polycarbonate plate that give inmold helmets a touch of refinement. It covers the edges on the underside of the helmet. This protects the Hi-EPS and increases the helmet's durability.

Proven a hundred thousand times over and used on all Alpina helmets: the strap buckle with the red push button and multi-step automatic locking mechanism. Ergomatic can be operated with one hand - you can loosen the strap on the way up the mountain and tighten it for downhill - and in a fall the locking mechanism cannot open automatically.

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.

MIPS is a system that provides protection against brain injuries that can be caused by rotational movements in an impact. The low-friction insert allows it to glide smoothly 10-15 mm in any direction, thus reducing the rotational movement in the event of a fall. This gives MIPS extra protection.

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 fixing of the two straps under the ear plays a decisive role. The Y-clip system ensures a millimetre-accurate adjustment - in a matter of seconds.
