Thickness?...
They seriously ask about “thickness” if you're looking at these you want breathability, not thickness. These are amazing. I have 5 or 6 of them that I wore for work, washed on weekends and then wore them again and again. They held up to a gentle cold cycle in my washing machine with jeans and other items worn for work. If we have to go back to wearing masks again, these are my go to.
