Our fabric is sourced from South Korea, it is a mixture of polyester and synthetic polyester from plants that have antibacterial properties (USA Patent: US 9125920). This provides a semi-permanent antibacterial effect which is longer lasting than copper or silver infused fabrics that oxidize and lose their antibacterial properties. Wearing a mask will become an everyday reality when social distancing measures are reduced. Our mask will provide a comfortable fit with reduced moisture and decreased bacterial activity. We have large size for most of adult male and medium size for adult female. Black colour and light ivory colour masks are available.
