Lorica masks are made with a single layer of scuba-type fabric with a center seam. Aerosols do not visibly penetrate them, and they have been tested to filter dust. I don't feel comfortable making the claim that my masks are going to make you impervious to any virus, but maybe they'll give you a little more courage to face the day. If they at least make going outside with a face covering one iota less dreadful, and one iota more powerful, I hope they're something worth making.

All masks have been washed once, but do consider washing a second time before wearing (especially if you are sensitive to certain detergents: I use Tide).
