I have never been able to wear the loop style headbands. They just slip off the back of my head. Ironically, buttoning a mask to the headband keeps my mask on and my headband on. The things we learn. The physics are all proper with the opposing forces and all that, it is just funny. I like that with the ear loops snug to the buttons, the elastic doesn’t push my glasses forward. I trialed a thinner headband, so thought I would try some waistband elastic and a wider tube of fabric. It works just fine.
