Perfect for everything but talking
Black mask is thin enough to qualify as a face covering but not so sheer as to get you in trouble.  Very breathable and comfortable as other reviewers said.  Perfect if you're working quietly and not talking.<br /><br />But...if you have to speak a lot in front of a group, moving your mouth, the mask can get moist and can stick to your lips and face.  Since my favorite phrase is "Sufferin' Succotash!" I use a different mask when I have to talk a lot, but this one when I just have to wear one (mostly silently) for a long period of time.
