For protection against insect bites, the front holes of some models are lined with a net.
That's the name for the outer shell of all ALPINA helmets featuring INMOLD manufacturing technology. This thin and light-weight material is extremely break- and scratch-resistant, UV-stable and antistatic.
The detachable shield protects against dirt splash as well as direct sunlight.
The inner shell of all INMOLD helmets is made of HI-EPS (High Expanded Polystyrene). It consists of a multitude of microscopic air pockets that absorb the forces occurring in an impact. In addition, HI-EPS absorbs neither water nor sweat.
Inmold helmets are produced by foaming the inner shell underneath the outer shell under high pressure and heat. Thanks to the complete bonding between the upper and lower shells INMOLD helmets are extremely sturdy and very light. In addition, they offer clearly more safety than spot-bonded helmets.
All ALPINA helmets are equipped with ERGOMATIC strap buckles. The anti-twist, automatic multi-step adjustment system is easy to operate using just one hand and prevented from opening in case of a crash.
