All masks have three layers. A outer layer of tightly woven quilters cotton, a middle layer of 100% spunbond polypropylene and a layer of soft cotton muslin next to your face. Washable, and reusable, these non medical grade masks are compliant with Health Canada's standard. Made in Canada with locally sourced materials.
I personally tested this product for breathability and comfort while out doing essential errands, before I put them up for sale. They are not harder to breathe through, which is good. What I did notice is that it doesn't move in and out as much when I breathe so I had no need to readjust it. So while it does the job, you don't notice it, which is what you want!
