This is a face mask covering the nose and mouth, while following the natural convex contour of the face. Most notably, the area at the mouth has a clear panel with rounded edges. Due to the cloth at the nose and the rounded edges of the vinyl panel, fogging incurred by moisture emitted by the nose & mouth is minimalized.
Mask is most effective in controlled temperature environments; not ideal for high activity that will incur sweating/heavy breathing. In case of fogging, it is effective to wipe a light dab of liquid soap/detergent to create a seal on the interior of the clear front.
