These masks are made from 100% cotton to make them comfortable and breathable.  They are double-layered and include a pocket for an optional filter (you can cut and use a coffee filter or even paper towel).  These full-coverage masks are incredibly comfortable with lightweight elastic at the ears.  The pattern used is The Olson, named after 1930’s legendary maker nurse Lyla Mae Olson, and was developed by clinicians from UnityPoint Health and is being shared across the globe in the fight against COVID19.  Since it was designed by medical professionals, many agree that it is the best pattern for home made face masks.  They are also machine washable and reusable!
