All our helmets have been proofed and tested by the CSI, a company, which is authorized by the Italian Ministry of Transport and recognized by the German TUV.
This company issues the certification for all helmets including ours, which are designed especially for free flight, in accordance with the European requirements (EN966).
Our helmets were conceived and are built expressly in a light way.
Nevertheless they are perfectly safe for hang and paragliding pilots, as the above information demonstrates.
According to the kinetic energy absorption laws, a shell that is too robust will not necessarily offer the best protection.
The optimal shell thickness is the one that will break at hard impact.
This same principle is used in the car industry, in case of a crash the front or rear part of the car will deform absorbing the impact and maintaining the inner cell of the car intact, protecting the passengers.
Therefore, the helmet’s shell should also break with a strong impact in order to absorb the shock and to prevent transmitting it to the head.
Due to the above reasons, it follows that all helmets must be handled and used with care. 
Please pay attention that the helmet during storage is not exposed to strong pressure, especially the chin protection and the sides, which are places where the helmet should eventually break in order to provide the necessary protection.
Moreover, if enough pressure is deliberately exerted on the helmet, the surface varnishing could split.
Cracks on the varnish around the facial area appear usually when the chin protection is strongly pressed backwards.
In case of very strong impact, the helmet MUST break in these specific areas!
