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 that are manufactured using the inmold process have a robust ceramic shell. A polycarbonate plate is stretched under high heat to the shape of the future helmet and pressed onto the Hi-EPS body with high pressure and thermally bonded to it. The Ceramic Shell is characterized by several qualities: It is break- and scratch-resistant, UV-stable and antistatic.

Custom Fit is an adjustment system at the back of the head that allows you to adjust the height of the Run System in several steps. This allows the optimal fit of the helmet to be adjusted for a wide variety of head shapes. Pressure marks are a thing of the past, the helmet sits perfectly on the head and safety is improved.

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 Inmold helmets consists of Hi-EPS (High Expanded Polystyrene). It is made up of a large number of microscopic air pockets which absorb the impact forces that act in a crash. In addition, HI-EPS absorbs neither water nor perspiration.

In the production process for Inmold helmets the inner shell is foam-injected underneath the outer shell under high heat. Thanks to the complete fusion of the upper and lower shells Inmold helmets are extremely stable and very light. In addition, they offer clearly more safety than spot-glued helmets.

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.

The Y-Clip connects the front and rear straps beneath the ear. Opening the clip enables the straps to be adjusted easily for a perfect fit.
