Alpina Thunder 2.0 MTB-Helmet | black-anthracite

The special model Alpina Thunder is a mountain bike helmet with a sporty look. It features 25 ventilation openings which provide a pleasant climate. The HI-EPS inner shell and the in-mold production process ensure safety. 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. 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. 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. Tried and tested countless times, this is the buckle used in all Alpina cycle helmets. It features a red push button and multi-step automatic adjustment. It can be used one-handed, so for example you can loosen the strap when riding uphill and tighten it again for the descent, and it will not open in the event of a crash. The detachable shield protects against dirt splash as well as direct sunlight. For protection against insect bites, the front holes of some models are lined with a net.
