We feel we accomplished those goals with our current mask, but as with all our products, we are always looking to improve. Customer feedback is an important part of improving product. While most have loved the fit, style, and comfort of the mask, some have expressed concern that the two-layered cotton fabric is too thin and makes them unsure if the mask protects as well as it needs to. We appreciate the feedback and are already working with our design and manufacturing teams to use slightly thicker cotton material in future versions of the mask. In the meantime, if you are someone worried about the thickness of your mask, we would encourage you to double up the mask, pair it with a medical grade mask, or resort to a different mask altogether.Care InstructionsCloth face coverings are an additional step to help slow the spread of COVID-19 when combined with other preventative measures and social distancing. The CDC advises washing cloth face coverings after each use. This means that even though our masks are reversible, they still need to be washed before wearing the reverse side. We recommend following CDC instructions for washing and drying your mask. Because our masks are 100% cotton, they may become wrinkled after washing, and their pleats may need to be ironed back into place. To avoid ironing, flatten fabric after washing and lay flat to air dry.Machine Wash Cold, Tumble Dry Low, Warm Iron if Needed, Do Not Iron Plastic Adjusters, Do Not BleachWhat is the Teca Cotton Face Mask’s Fabric Blend?Per the CDC’s recommendation, our face masks are made from 100% tightly woven cotton.Is the Teca Cotton Face Mask Medical Grade?Our face masks are not medical grade.
