AIM Shell (Shoei)
The AIM (Advanced Integrated Matrix) Shell consists of 5 layers; Fibreglass, Special Fibres, 3D Organic Fibres, Organic Fibres and Fibreglass. Comparing this shell composition to a helmet made only of fibreglass, the AIM Shell is lighter and more elastic but also maintaining the same strength. The synthetic resin used within the helmet shell is extremely resistant to corrosion. This shell design allows impacts to the helmet to be absorbed through the many layers of fibres and distributed over a larger surface area of the helmet. This can mean that after a strong impact to the shell you can notice damage to the shell and the EPS liner, but the head of the rider is given maximum protection due to the way in which the impact was dealt with.

AIM+ Shell (Shoei)
The AIM+ Shell has one extra layer compared to the AIM shell. The six layers of an AIM+ are; Fibreglass, Special Fibres, High-Performance Organic Fibres, 3D Organic Fibres, Organic Fibres, Fibreglass. The properties are the same as the AIM shell but with the added High-Performance Organic Fibres, the helmet will be stronger and can deal with impacts even better than AIM shell helmets.

EPS Liner (Helmets)
