Birds Hummingbirds Shorebirds Adult & Childrens Masks Face Coverings

Samples of our masks were tested by engineers & rated better than some commercial brand medical use surgical masks. "As the person who has been donning all the masks, I really appreciated the comfort & adjustability of the ear loops. The finding that the nylon layer didn’t improve the particle removal percentage means that the mask fits well as designed, & the breathing air is passing through the mask rather than around it."Machine washable, adjustable soft stretch knit ear loops, moldable nose piece, 1 layer cotton/polyester, 1 layer Pellon 50 sew in interfacing, 1 layer print or solid color. I am trying to keep this up to date.
