We generally wear cloth masks that I make. But I make them with two layers of silk (natural electrostatic properties that help attract and trap) as well as an interior 16 MERV filter fabric that is washable. I custom fit them for each member of the family, so they fit more snugly than most commercially made masks. On flights, we have opted to double mask with an N95 and the cloth mask.
You are talking my language! I sewed hundreds of masks, mostly pleated, for donations, but for my family, I worked hard to customize them to the individual. I made at least 12 different patterns and settled on the batwing for me and my daughter who teaches special ed. I have our KN95s and surgical masks for when we need them, but I will also be bringing my great fitting, comfortable cloth masks to wear under my KN95s and maybe alone, at times.
I have custom fitted my KN95s by trimming the edges a bit, cutting and adding more elastic and adjusters to the ear loops, and adding a larger loop of elastic so I can remove the mask and it will hang around my neck.
Thank you for all the responses. I live in a rural area of Minnesota where, except for medical facilities, mask wearing has become almost non-existent, so I really wasn't sure what to expect to see when traveling.
