Review on WonderFabric: Innovative Reusable Construction Material – Washable, Breathable, and Comfortable! by Aaron Thawngzauk

These are great masks, well made and very comfortable. I ordered an adult size which is perfect for me but may be too small for some adults. Fortunately, there is also a very large size. The fabric is thin so I wear it with filters (there is a slit for the filter). They fit snugly to the mask, which is what you need, but not too tight. They also have a nose clip which helps ensure a good fit and reduces fogging when wearing glasses/sunglasses. I will order some very large masks for my husband. I highly recommend this item.
