Full Face Diving Masks cover the scuba diver’s entire face and have some special features not found in standard dive masks. Using a full face mask allows the diver to breathe from both the mouth and nose, results in less fatigue because the diver does not have to bite down on a mouth piece during the dive. They are excellent for colder water, do not require defogging and are almost impossible to flood. With the addition of a communication system you can even talk underwater to other divers.
