Abstract
A valve mounted on a dive mask is disclosed. The mask has a closed window frame, a soft skirt extending rearward from the window frame for defining a space between itself and the face of a diver wearing the mask, and one or two windows defined by the window frame. The valve is flexible, tubular and has a first opening at one end in communicating with the space, and a second opening at the other end. The second opening is blocked in an inoperative position and is adapted to open to expel water or air therethrough by increasing pressure in the space or by pressing both sides of the valve.
