Sizing: Our masks are petite and fit nice and snug. Most of the masks we tried on or found available were really big, so we went with a size that we consider to be "small." Based on the shape of our mask, the measurement for the top of the mask is wider than the bottom of the mask. It helps the mask better fit the shape of your face!
Material: Made of microfiber, nice and soft. Launders like a dream, machine wash and dry, no problem.
Note: These masks do NOT have a pocket or filter liner.
