In my country ( nordics with mask mandates ) the single layer mask is explicitly forbidden and is scientifically proven be worse than no mask at all, as single layer cloth disperses droplets making spread worse.
I would be kicked out of any store if I wore a single layer mask.
In other countries the same scientific dogma states that single layer is not only allowed but even recommended as better than nothing.
Sigh...

What kind of material causes more dispersion than nothing?
Most serious coverings were more effective than nothing. And from what I've seen any fashion/joke-only coverings were denied or criticised immediately.
