airflow

The little plastic hinges that swivel out to create airflow are well built—they’ve never broken on me or gotten stuck during thousands of deployments on the resort or in the backcountry.

The goal of all of these options is to direct airflow through the mask, rather than allowing aerosols to leak around the sides.

If you’re going for intense, grill-like heat, this extra bit of airflow will release any steam that could otherwise be trapped and prevent immediate browning.

The radiator and brake ducts can close while driving to promote more airflow around the body.
