These masks look nice on your face and ear loops can be adjusted to fit. However, it is almost impossible to breath through them. I bought 4 of these, and keep them in the car in case I forgot a mask. If you wear glasses, it definitely fog up the glasses.
Good fit. My head is too big for some "one size fits all" masks. These are adjustable and fit well.
The mask layers are thick enough to make it hard to breathe heavily. It gives me confidence the mask is working well.
The mask feels good when worn for extended periods like through airports and on domestic flights.
I was hoping these masks would be free breathing and could be something I could comfortably wear when pushing myself on the bike. They are not. There is very little air passing through the fabric. If you wear glasses they will be steamed. These are fine to wear at work or to the store, but because this was offered through this store, it would be good for cycling. I did not find that to be true.
Sooo...I have used dust masks, paper masks, surgical masks, homemade whatchamacallit masks. You get the idea. So far these have been the most comfortable masks because the straps that go over and under your ear are adjustable independent of one another and the higher nose keeps it in place.
