A full-face diving mask is a type of diving mask that seals the whole of the diver's face from the water and contains a mouthpiece, demand valve or constant flow gas supply that provides the diver with breathing gas.

An alternative to the diving helmet that allows communication with the surface is the full-face diving mask. These cover most of the diver's face, specifically including eyes, nose and mouth, and are held onto their head by adjustable straps. Like the diving helmet, the full-face mask is part of the breathing apparatus. [5]
A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including scuba divers, free-divers, and snorkelers, to see clearly underwater. [1] [2] Surface supplied divers usually use a full face mask or diving helmet, but in some systems the half mask may be used. [2]

Such helmets have an open cutout in a band across the eyes and nose, and often include a clear or tinted transparent plastic face shield, known as a visor, that ...
In a helmet equipped with the MIPS safety system, a low-friction layer allows the helmet to slide relative to the head, resulting in a reduction of the rotational motion that may otherwise be transmitted to the brain. In this way, the MIPS approach mimics the natural safety system of the human head. [4]
