In one embodiment of the present invention a water activity mask has a transparent visor and a pliable frame defining an interior volume. One end of the frame rests flush against the wearer's face, forming a substantially watertight seal. The interior of the mask contains a fluid directing member extending towards the visor from the inner surface of the mask. In use the fluid directing member normally retains and prevents liquid in the mask from coming into contact with the wearer's face. The liquid is generally used to defog the mask as necessary.
