Folded over so many times I can't believe that the breathability would be any good.
Yeah, that's freakin' insane... One step away from strapping a pillow to your face and smothering yourself.
Here in the real world, I went out yesterday wearing a bandana "cowboy style"- folded in half corner-to-corner and tied once in the back, the way cowboys wore them to keep trail dust out of their mouths and noses when driving cattle.
Not all bandanas are created equal and the one I wore yesterday was a relatively thick one with a fairly tight weave (Some cheap bandanas are almost gauze-like). I could definitely feel the restriction in my air intake when I breathed in with it on and under no circumstances would I want to try to run a marathon while wearing one. It didn't take long to find out that breathing in through my mouth and out through my nose was the most effective way to do it.
A good ol' bandana may not be not THE most effective protection overall, but it's a damn sight more effective than the official masks when they either have huge gaps beside the nose or on either side near the ears or if they're worn over the mouth but not the nose meaning people are breathing around those masks and not through them, thus rendering the masks completely useless.
That is precisely the conclusion these folks drew: https://www.cidrap.umn.edu/news-perspect...sound-data
The problem is that for cloth to reach any sort of effectiveness, it's likely it'd be so thick that you can't easily breathe through it.
