C. THE HELMET
VENTILATION SYSTEM 4 – HEAD VENTILATION
There is a large air inlet cowl with a three-
stage adjustable ventilation system on the
top of the helmet shell for ventilating the top
of your head. Air entering the helmet through
this inlet cowl is directed via channels to the
top of the head. Inside the helmet, the head
padding system enables direct contact between
incoming air and the surface of the head,
thereby conducting the heat away from the
inside of the helmet quickly. The ventilation is
adjusted by means of a slide on the air inlet
cowl that is easy to operate even when wearing
gloves. Moving the slide backwards to the first
locking position produces partial ventilation,
moving it further back opens the air inlet to
its full extent.
SUMMER AND WINTER ADJUSTMENT FLAPS
The ventilation of the C5 can also be adjusted to suit the seasons, weather
conditions or your personal preferences. While you will prefer the cooling air
current to flow directly on to your head in summer in autumn/winter you can
reduce the volume of incoming cold air, or divert it, by covering the ventilation
channels with the flaps of the head pad. To do so, raise the head pad and fold
out the fabric flaps located behind the front section..
