Very breathable
I can repeat what all have said: thin, not see thru so no one knows it's so thin, highly breathable. I've worn this mask exclusively since purchase, comfortable, looks nice. Hand washes & air dries quickly. The only problem I have is this is the only mask I've used that gives me a face rash. I'm thinking it's the slightly rough nature of the material, not sure.
