Manageable even with arthritic hands
My favorite masks come from an Etsy seller who makes them with adjustable head cords -- a loose one across the back of the neck, and a tighter one around the back of the head.  They're great when you want to take your mask on and off quickly, like passing people on an exercise walk. This cord gives ear-loop masks almost the same convenience though not quite as much comfort behind the ears.  The one negative is that the plastic connectors are tiny and hard to open when you want to attach the cord to a new mask.  I suspect they'd be nearly impossible for someone with arthritic fingers to use.<br />I've discovered it's possible to force each cord through the catch, without trying to open the connector with my fingers.  Like these enough that I bought two more.
