Another feature of the trigger mechanism is that with the absence of sideplates, noise reduction is improved. The RF-800 is one of the quieter helmets we've worn. Venting is good, although it could be better. Basically, the T-VENT is supposed to allow for more frontal air intake by increasing the the flow of the air coming from the lower intakes just above the chin. In theory, increased airflow at the upper intake will force more air through the lower intake and offer more comfortable shell temperatures and less shield fogging.
Shell temperatures are very comfortable and air flow through the upper air intake is excellent.
However, air flow through the lower air intake could be better. If you stop in cooler weather and the visor fogs from breath condensation, the shield must be open a crack before it clears up. Although this happens to every helmet, it seems to happen to readily on the RF-800. Luckily, the face-shield system has a preset opening lever that is easy to operate with gloves. Skid's favorite lid.
