Great for actual breathing
As a person with multiple lung issues who is forced to mask up (against my doctors orders) if I want to keep my job I was looking for the thinnest mask available. So far this mask is it.<br />I have several others made of cheese cloth type material but they are two layers. This mask is only one layer of medium woven cloth. I purchased black and the thinness is undetectable while wearing.
