I read that 3 fabric layers were better than 2 several months ago, its not new. I've even seen a comparison chart for different fabrics. As I said, it was a long time ago so I can't give sources but it might have been in The Times ( UK ).
This coronavirus hasn't been present in the worldwide human population for 5, 10, 20 years so the science around it
has
changed and is still changing. Therefore the advice given by the experts must also change as new things are discovered.
