What is the Raid airflow system?Updated a year ago

If you look at your goggles you will notice two notches in the top portion of the frame, then look at your helmet near where your forehead will be you will also notice two open channels between the outer shell and the interior of the helmet. These channels run through the entire helmet and they line up with the notches in your goggles, this allows constant and clear airflow through the helmet keeping your goggles from fogging up, and your helmet from overheating.
