Should be rated Amazon's best seller!
I have tried several different cloth masks one was great could breath ok but after awhile hurt my ears, another fit perfectly but couldnt breath,  I even purchased mask lanyards to relieve ear pain from long time wearing and keeping it handy around my neck when not in use.  This mask is exceptional in every way, comfort, breathability, soft, no ear pain, adjustable and convenience that it will be there when you have to quickly remove and replace it!  Easy adjustments with the pull or tug of the neck string. Comes in all different sizes child's, adult large and adult xxl. I ordered and received the large and it fits perfectly !!  A little on the pricey side @ $14.99 but I took a chance and ordered a large in white, they have black also,  now after wearing mine all day I ordered the 4 pack!  They are worth every penny!  This mask is also able to hold the filter if you want (sold separately). All in all I would vote for this mask to become.  Amazon's best seller and Amazons choice
