7-11 for the range of application (Fig. 7-11). The shield technology
is printed in the middle on the upper edge of the visor (Fig.
3). If nothing is printed there, then the shield uses "Singleflex"
technology. All ski helmet visors are equipped on the inside with
an "anti-fog" coating. Quattroflex shields have been specially
developed for skiing and have a polarisation filter deviating from
the EN 174 standard. Extensive practical testing – mainly in
professional racing – has confirmed that this deviation ensures
ideal contrast enhancement and makes surface structures more
visible. A few shields are equipped with a high-quality reflective
coating ("Mirror") on the outside. This high-quality shield coating
is sensitive to scratches and therefore requires particular care
during cleaning and storage. Scratches in the reflective coating
are excluded from the warranty. 2. Use, Maintenance and Transport:
Before each use and after every fall, the visor should be checked
for any damages to the visor, visor attachment or nose guard and
replaced if necessary. Visors must be replaced if the intended
use can no longer be guaranteed because they are dirty or worn.
After use, the visor helmet should be dried at room temperature
and stored in dry and dark conditions in a container meant for
it, such as a box or bag. Extreme temperatures, such as over
50 °C, should be avoided. 3. Cleaning and Disinfection: Clean the
visor with a lot of water and without additives. Do not treat with
solvents or household cleaners. To clean, use lint-free cloths. Only
shake the water off the visor; if necessary, dab with a cloth and
let air dry. The inside of the visor has an anti-fog coating. This is
sensitive to scratches. For this reason, please treat it with care
and never wipe it off. 4. Attaching/Removing the Visor: For many
of our visored helmets replacement visors are available, featuring
