Yes, some are designed with water-resistant outer layers. The good ones. Single ply facemasks though? If you wouldn't use single ply on your butthole, don't use it on your face.
Current CDC guidelines for cloth masks stipulate MULTIPLE LAYERS. This shit shouldn't even be sold.

The only exception is if it has some kind of way to hold a sheet of filtering material. We use some cut up vacuum bags as filtration.

These are better than wearing no mask, but there are definitely better options. There's another deal posted on this site for 1AK's. $14 for 50. that's a good deal. I also bought KN95's to wear for real protection. There are a lot of different brands out there that make really poor quality masks (like these reusable ones), but i found a good one - raxwell.us

Those vacuum bags probably aren't doing much. Most of the HEPA bags are designed for pressures produced by a vacuum, making them very difficult to breathe through. When used in a cloth mask, the vacuum bags redirect air out the sides rather than through the filter material. "Meltblown" fabrics are supposed to be best, but eBay and the like are inundated with questionable stuff, so it's difficult to find anything decent. The best readily available material is Halyard H600.
