A Face-covering is the new accessory!  These are made of 100% Cotton. They do have a little slot into which you can add a filter of your choice if you wish. 

The good bits ...

They are soft but not too close fitting allowing the air to circulate ( so no misty glasses)

The elastic is soft and flexible so not gripping your ears.

They are jolly and inexpensive so you can have a collection!

They are handmade. 

Of course washable at 60 deg. if necessary.
