This is a listing for a two-layer cloth mask. This mask comes with unfinished elastic, or a cord loop with adjustable cord lock. This mask has no pocket, but has a good fit because it has a chin piece.
Cloth face masks are not be intended to replace medical grade equipment. They are not approved by the FDA for any sort of protection against anything. The CDC and the FDA are NOT on the same page about this, so please keep that in mind. The CDC, and several other agencies, are pushing for cloth masks because they are absolutely better than nothing (studies showing at least 40% better than nothing). Again, for those in the back: Cloth Masks are not guaranteed protection against ANYTHING.
