hi everybody,
a wellknown dealer sell a helmet with an interesting ventilation system.
four ventilation holes are in the liner, two on the helmet under the spike basis. An opening has been done under the rear spine, and two at its basis with an ingenuous system to hide them.
do you have already this type of ventilation system ?
In your opinion when is this from?
thanks
