about how they're working out?
They don't have ear loops. There are two stretchy bands that go behind the head, one near the nape of the neck and the other higher up, just below the top of the head. That gives a good seal on the face, with zero gaps.
After I get the upper band in place, I lift some of my hair up from under the band to let it fall over it. Looks better on me that way. Or, I can let both bands rest at the nape and pull the upper one up to loop over the ears on both sides. On my face, it still gives a sealed fit that way, without any gaps, but I don't know if they would work that way on other faces. The fit is very snug.
They are more breathable than double masking, and very comfortable. The front sticks out firmly and reminds me of a bird beak so that the edges are the only place where it touches the face. There is a metal band at the bridge of the nose to bend for a close fit there.
It is so lightweight and thin that you might wonder how it protects you, but it actually has 5 thin layers of nonwoven, fused substances designed to filter out particles. That's two more layers than a surgical mask and with a sealed fit that surgical masks don't have.
It comes with each mask in its own sealed plastic wrap so that you can carry it with you in a purse or pocket.
