All of the ones which have elastic ear loops are pants. Absolutely agonising after a day with bands behind your ears. I have made a sort of cloth strap which catches the ear straps on a button at each side, but loops round the back of my head, taking up the tension which would normally just pull on my sore ears. Also, I use a continuous paracord, which threads through tags at the side of the masks and tensions with toggles at the back of my head -good for pulling on or off without faffing with ties. I have made bloody loads , with various styles, shapes and materials and am now sick to death of them. I knocked up an origami shoulder sack, for a treat. Has got me right back into sewing though.
