RIAS – Rotation Impact Absorbing System (fig. 5) is the
revolutionary Diamond helmet technology: In addition to
dissipating compression-absorbing shocks like traditional
helmets (linear impact), the helmet structure combines
innovative technology that dissipates the energy associated
with rotational acceleration (rotational impact), reducing
tension and providing additional protection for some types of
impact. This is all possible thanks to the combined work of the
different layers of material used:
The main inner shell (fig. 5 - A) in high density EPS is
characterised by a very compact, rigid outer surface (in
contact with the outer shell). The inner surface has large
grooves that offer a dual function: they provide greater airflow
and differentiate impact force dissipation, effectively as if the
main layer had two different densities.
