    looks great

    I love it.
    I use it while jogging and it’s very breathable.
    Most of the masks are not good during exercise when your sweat forms a film making it barely breathable. Fortunately, it doesn’t happen to F1S.
    I also tried wrapping the mask around my PM2.5 meter and I got a significant reduction in PM2.5 reading. It’s not a scientific measurement but it shows that it’s good enough for me.
