Hearing Aid Friendly
The elastic loop is not sewn directly and is free to slide through the mask's side "tunnels".  This an excellent feature for we who wear hearing aids.  The mask can be put on and taken off with minimal interference with the aids.  Competing mask designs that hook around the ears are not at all good with hearing aids.  The chin and head portions of the elastic loop both can be shortened with a single knot.<br />One feature that would be good to have added is an adjustment pad or buckle to use in place of tying a knot in the elastic.  This could also serve as an "anti-slide" feature on the top of balding heads.
