Abstract
A mask is made of a single piece of flexible, elastically deformable fabric trimmed to be substantially symmetric. The mask includes two flaps connected to each other along a center folding line. A V-shaped cutoff is formed above and below the center folding line between the flaps. The single piece of fabric is bent along the folding line with the flaps overlapping each other. Side edges of the flaps that define each V-shaped cutoff are sealed together by means of sewing or adhesives whereby an interior space is formed between the flaps and defined by the center folding line and the sealed side edges of the V-shaped cutoffs for comfortably accommodating the nose and mouth of a wearer.
