Here's a front view of the N85 platinum silver solid helmet; features are basically the same on the graphic helmet models.
Air intakes located on the front part of the shell allow for air flow into the shell; it doesn't matter if the internal sun visor is lowered or lifted.
The lower air intakes help to keep your shield from fogging.
This view of the back shows the large exhaust grid located in the spoiler.
The VPS internal sunscreen is easily operated and can be removed for cleaning or replacing.
And finally, the helmet is ready for the N-Com communication system should you wish to add that capability (sold separately).
