Absolute Gold!
These masks are a life saver when you have to wear one every day.  You can breath right through it with ease.  I bought three different “breathable mask” types and this is by far the most comfortable and breathable.  I am also willing to pay a bit more for them due to them coming from small US owned family business (Out of AZ I believe).  No issues with fit and the do not pull on your ears.  They are ABSOLUTE GOLD.
