Staples has a really good deal right now on this 10 pack of 3-ply cloth face masks (adult size) for just $29.99 plus free shipping or free instore pickup. The fabric is 100% cotton, washable, and the earloops are adjustable so you can customize your fit. The pack offers assorted colors and prints.

I actually bought this pack for my family and they fit great, very comfortable around the ears, and wash up well.
