Under each grid there are 3 holes that
pierce the polystyrene, so that air can
enter from outside. If you don't wish
this airflow, you can just close from
inside the helmet the holes with some
adhesive tape. Cut, a helmet built using
the same technology as in military applications, including high-modulus glass fiber and high-density
polystyrol to guarantee the highest possible standards of safety. We sell this helmet only with the visor. All our visors are antifog, antiscratch and have full UV protection.
