Face masks are 3 layer, the outer two are cotton with a middle layer of nonwoven polypropylene to increase filtration. Comes with adjustable ear loops for the perfect fit.
This is one of the best masks I have worn since the beginning of the pandemic. The mask is extremely well-made and comfortable. I particularly like the fact that there are separate sections that cover my nose and chin-it makes the mask comfortable and functional. Plus, the fabric design is awesome for a scientist!
