(2-Pack) Tempered Glass Screen Protector

It's very simple to use and fits adults. I wear it during workouts, and it keeps my glasses on and dries fairly quickly after. It's not gross. It does leave my head feeling warmer than usual, but that's to be expected. My glasses are plastic rimmed. I don't know if the strap would fit as well if I had smaller (thinner) wire frames. But it works well on the bigger plastic ones.
