Abstract
A clear plastic visor (16) is secured to a mask (12) which is removably attachable to the face of a wearer. The visor (16) is secured to the mask (12) at bond areas (48, 50) on opposite ends of the mask (12). The visor (16) is provided with a notched keyhole (20) to allow the visor (16) to conform to contours of the face of the wearer and to prevent creasing thereof. The visor (16) is generally positioned on the mask (12) so that approximately 1/3 of the visor's depth (D) covers the mask (12). A darkened strip (22) may be added to the top edge of the mask (12) to further reduce the likelihood of glare and reflections.

- a gas pervious but substantially liquid impervious mask formed from a plurality of material layers disposed adjacent to each other;
- said material layers comprising a barrier which is capable of differentiating between gases and liquids, whereby gases may pass freely in either direction through said barrier while restricting the passage of liquids from the exterior of said mask;
- a pair of connections formed between said mask and said visor by bond sites at opposite corners of said visor and said mask whereby said visor may be positioned over the eyes of a wearer;
- and
- means for improving the fit of said visor, said means comprising a lower edge of said visor having gradually sloping arcuate edges at opposite extreme lower corners of said visor where said gradually sloping arcuate edges extend below the central portion of the lower edge of said visor and are the only bond sites between said visor and said mask.
