Fog-Free™ design redirects hot air out toward the sides of your mask, venting it safely away from your lenses. No more foggy glasses! Exhaled air follows the path of least resistance. Most of the time, this path is out of the top of the mask, straight toward your eyes and eyeglasses.
Fog, fog and more fog!
Fog-Free™ creates a comfortable barrier that fills the gap between the cheek and nose and redirects the air outward towards the side of the mask.
This prevents eyeglasses from fogging. We have tested to ensure that all face shapes get the most comfortable fit and best seal possible.
