Size guide: L/XL fits an average male face, but also fits a larger female face. S/M fits an average woman’s face, but also fits a slim men’s face. We have developed a 3-layered face mask as a sustainable alternative to disposable face masks. The face mask is high quality, with an outer and inner layer of organic cotton and an intermediate layer of melt-blown non-woven polypropylene filter. It is reusable and can be washed, see washing instructions at the bottom of the page. Do not tumble dry. Note: Our face masks are not categorized as safety equipment, personal protective equipment nor medical equipment. We believe that medical and professional protective equipment should be prioritised for health personnel.
