ABSTRACT A mask arrangement particularly adapted for use in cold weather conditions includes a mask member and a spaced eye shield. Air flow directing means directs air flow between the eye shield and the mask member, providing comfortable air flow and inhibition to fogging of the eye shield. The mask member is divided into a vision region and a breathing region. The vision region includes a port therein covered by the eye shield. The breathing region is generally isolated from the vision region and includes a breathing aperture with baffle means associated therewith. In a preferred embo- diment, the breathing aperture comprises a large aper- ture in the central portion of the breathing region, with the baffle means comprising a baffle plate mounted over the breathing aperture. The baffle plate generally deflects air preventing jetting directly into the mouth of the wearer. Relative constant spacing between the eye shield and the mask member facilitates air flow without substantial turbulence.
