SUOMY apex Instructions D'utilisation page 21

The internal shell 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 APEX ventilation system, along with the particular shape of the internal polystyrene shell, optimizes outside and inside air flows, fed by
air intakes, which exploit the Venturi effect thus optimizing internal ventilation. The back deflector was designed to reduce the vibrations on the
helmet, moving as far as possible the "detachment" point of the aerodynamic flow. This limits the vortexes that are formed when a body hits an
aerodynamic flow and it also improves the elimination of the flows.
Furthermore, it assures an even distribution and continuous internal ventilation of the shell.
The strap is fitted with a D-ring closure (Suomy patent) made of anti-corrosion stainless steel with strap fastening button. The fastening is in
a completely free and accessible area. It is easy to fasten and unfasten even with gloves: when the automatic button is fastened the strap forms
a hoop that can be used easily as a «ring» to pull the release tab and unfasten the D-ring closure system.
