How do Smiths AirEvac 2 and AirEvac technologies help with ventilation?
AirEvac 2 utilizes shell vents as well as internal EPS channels to increase airflow ane evacuate warm, moist air to prevent goggle fogging. Cool, dry air is consistently pulled into the goggle as the warm, most air is exhausted over the wearer’s head and out the rear of the helmet. AirEvac uses a system of shell vents and under-shell EPS channels to actively pull warm, moist air out of the user’s goggles and exhaust it out of the helmet to prevent fogging.
