The better the helmet adjustment, the higher the
level of safety.

Temperature of use
The product (dry state) may be used permanently
in the temperature range of -40°C to +50°C.
Duration and replacement
The duration of the product depends on the
typology and frequency of use and well as on
external factors. Although not used, the helmet is
subject to ageing due to the intensity of UV rays
and weather conditions.
Normal use
Duration in case of normal and proper use,
without evident wear marks and under optimal
storage conditions: 10 years.
Maximum duration of the product under
optimal storage conditions and if not used:
15 years.
Very frequent use
or under extreme conditions
If the product is used under extreme conditions,
very high or very low temperatures, sea water,
or if exposed to frequent blows and shocks due
to the fall of stones/ice and if it presents many
scratches, its safety features could be reduced
even after a brief period of use so that the product
should be replaced. This helmet is designed to
absorb the energy after an impact. The absorption
of the blow occurs through the partial breaking
or damaging of the shell or the internal part of
the helmet. After a strong impact (blow, fall from
height; mechanical impact) the helmet must
be replaced even if it does not present visible
damages. The same applies in the case of deep
