masker-aid: 3 layer cotton, reusable, reversible, breathable, unisex adult face mask (over head m/l/xl, sage) kiyonna as an american manufacturer for 24 years, we knew it was in our dna to engineer and provide people everywhere with the best solution for a protective face mask. our 3 ply cotton, reversible, reusable, washable unisex cloth over the head face mask is comfortable and stylish while providing protection for both men and women. created in consultation with a local hospital, our multilayer masker-aid masks meet cdc recommendations for cloth face coverings. each mask has three layers. two layers of soft cotton comprise the outer layers and the natural fibers promote breathability without restriction. the tightly woven dual layers of cotton help prevent particle infiltration internally and externally. an internal permanent filter layer provides additional barrier protection from dust, smoke and more. after exhaustive testing, we achieved a snug, comfortable fit against the side of the face as per cdc guidelines. we engineered a contoured, formed fit around the nose bridge to fit snugly across the cheeks, below the chin, and from ear to ear. even though each mask has a fitted silhouette, the curved front allows for a roomy area around the mouth, making breathing easy in this triple layer design. adjustable double elastic bands that go around the head are perfect for those that need a large or extra large / wide fit and act as an alternative to face masks that tie behind the head. anyone looking for face masks for hearing aid wearers will find our face mask with head straps hearing aid friendly. for glasses wearers, we created a non fogging experience with contoured fit around the nose. our solid sage green mask is a great shade to wear with most everything. we wore our designs for hours to ensure you could too! your support helps us provide aid to our local homeless population who is in desperate need of protection. we are all in this together, and together we will overcome. hand wash gently with household detergent, lay flat to dry. wash before wear.
