This is not a filter pocket Olson style mask. It's two ply, washable, reusable, and looks super cool! The outer layer is made of a polyester/spandex blend and is so soft! Inner layer will be a solid color cotton. Even without a filter these do a really good job keeping your possible germs to yourself and keeping any airborne pathogens out of your nose and mouth.
Half Skull/Scorpion/Sub Zero Mask
I recommend washing all handmade items in a garment or mesh bag, to preserve the integrity of the seams.
