The Kitsbow Face Mask is an all-day comfort face mask designed specifically for users that work many hours, and don't want to add to environmental waste by disposing of their mask after each use. Instead, you wash it and use it again. Along with high-quality fabric and elastic selected by Kitsbow product designers with years of apparel experience, this mask offers an internal pocket for an optional filter. The filter can be removed when the mask is washed, and additional HEPA-type filters.
