FEATURES
The inner liner can be totally removed. It is made in excellent
anallergic fabric with anti-bacteria treatment.
All the parts in contact with the face are easily washable.
Interchangeable side cheek pads, available in different thicknesses
to assure the best fit for all head sizes.
The MX SPEED PRO ventilation system along with the particular
shape of the internal polystyrene shell, optimizes outside and inside
air flows, fed by three air intakes, which exploit the Venturi effect
thus optimizing internal ventilation. The four back air inlets release
the air flows. This assures a more uniform and continuous flow of
air inside the shell, which is also enhanced by the extraction grid on
the back part.
The strap has a D-ring retention system in anti-corrosive stainless
steel, and a button on the strap. The fastening stud is positioned
in a completely free and accessible area. The stud is easy to lock
and unlock even with gloves. Thanks to the particular shape of the
D-Ring system, the retention system can be easily disengaged even
while wearing gloves: when the automatic button is fastened, the
strap forms an eyehole that can easily be used as «ring» to pull the
tab and release the D-ring fastening system.
