Anti-bacterial + Washable Mask to help you gear up and protect yourself! Unlike the other surgical masks available on the market, Estope mask uses an anti-bacteria tested fabric based on silver ion technology (a specialized texture known as ATB-UV+) to prevent the bacteria and virus from passing through. In the midst of COVID-19 and the constant shortage of disposable surgical masks, Estope mask could be your best protector against all the harmful bacteria and viruses.
