Fabric washable face masks.
This style is a one size fits most and the elastic is easily knotted for smaller faces.
*NEW* Face Masks with adjustable elastic. If you think you have a bigger than average head I would recommend these.
These are double layered and have a pocket for a filter. A folded up paper towel works well for this, just remember to remove before washing.
The elastic is thin and soft and can be knotted to be made smaller for younger people. This size will fit intermediate school age children and up.
This design sits high on your face with good coverage and I can sit my glasses onto of the mask to reduce fogging.
