These face masks are essentially made up of 2 layers. The top layer is a high quality stretch fabric covered with sequins, fur or printing. The linging material is an open cel 1/8" foam/mesh to make breathing easier while still providing a barrier to incoming/outgoing air pollutants. ( see photo )
There is also soft 1/8" elastic with an adujuster for better fit used to go around the ears. ( see photo )
Please be aware that they are not as effective as the N95 version in fitering out contagions and should not be considered a replacement. However, they are likely to be more effective than just fabric.
These masks are made one size fits all with adjusters on the elastic around ears to make tighter/looser. There is a top and bottom to fit the face better, the smaller seam is on the top to accomodate the nose and the longer seam is on the bottom for the chin. I've also placed the logo on the left side of all of them to help distinguish top/bottom.
This product should only be washed by hand in warm/cold water and left to air dry.
