Each mask is unisex and cut and sewn locally and we have chosen to offer them at a price that hopefully is attainable to anyone who needs a washable and reusable mask.
Our size recommendations are here:
S/M - For smaller framed faces. This is the size I wear and that most women with an average size face and bone structure will prefer.
M/L - The model here wears this size, which is pretty standard for most adult men and also women with a larger face and bone structure. if you can't decide whether to get the S/M or the M/L, you could also choose to tighten the elastic on this by knotting or snipping and restitching, and that would work for someone in between sizes, or who cannot decide.
L/XL - If you are a husky man, get this size.
