This is a Remix of Ken Lord's design, based on feedback I received from Doctors and Nurses I knew that I'd printed for.  They requested a way to keep the band from moving around/flying off while attempting to put on or take off their masks.  I incorporated a section of hair pick so that the part can be inserted into the hair, where it will stay on it's own, allowing both hands to be used for putting on or taking off the mask.
