A premium face mask that they'll actually want to wear. Focused on fit and quality, the Proper Cloth design team has worked hard to create the most attractive, comfortable, and effective face masks available. This mask is crafted from a soft, breathable navy cotton and linen blend and treated with an antimicrobial finish for extra protection. Nested between the two layers of fabric is a hand-washable, removable filter made of 3 layers of non-woven polypropylene. A moldable metal piece at the bridge of the nose, plus elastic straps that wrap around the back of the head and neck makes for a secure fit.PRODUCT DETAILSHand sewn from black 70% cotton/30% linen blend plain weaveAir filter for virus protection, lab test certified to BFE ≥95%Non-toxic antimicrobial treatment to inhibit growth of bacteria and virusesOver-the-head elastic bandsABOUT THE BRANDFit and quality have always been the driving forces behind the Proper Cloth design process, and we're excited to bring that focus to face masks.
