Great addition to use under your mask
What a difference having this silicone bracket inside your mask. I love that this is very sturdy and thick but lightweight. I placed it on my mask and tried it for a couple of hours while I was doing my grocery errands. My glasses did not fogged up. I can breathe easily .  It didn’t bother me at all... highly recommended to have this additional gadget under your mask.
