A Note About Full Face Masks

Full-face snorkel masks are designed to cover your entire face, letting you breathe out of your nose and mouth. These types of masks are gaining in popularity, but there may be risks associated with their use. Like traditional snorkeling equipment, full-face masks can create dangerous carbon dioxide buildup. The tighter fit of full-face masks can make them harder to remove during an emergency.

When using a full-face snorkel mask, it is advised to breathe only through your nose. If you breathe through your mouth as you would with traditional snorkeling gear, there is a tendency to hyperventilate. In addition, diving more than 2-3 feet below the surface while using a full-face mask may not be possible and may become uncomfortable due to increasing pressure from the large airspace inside the mask.

If you are renting equipment, rent only from a licensed vendor, and talk to them about using this equipment properly. More info
