Abstract:
A face mask for improved fluid resistance is provided. The face mask may include a body portion with a first layer and a second layer. The first and second layers may have a plurality of folds that form a plurality of first creases in the first layer and a plurality of second creases in the second layer. The body portion may have an outer facing surface and an inner facing surface opposite from the outer facing surface. At least one of the first creases may be misaligned with at least one of the second creases in order to provide improved fluid resistance of the body portion.
