5 stars for quality, 3 for comfort. It's excellent quality - in the design, the materials, the craftsmanship. But it's not very comfortable, especially when worn as a mask. I got the L/XL and it is so tight my nose is pressed flat and I have trouble breathing. Yes, I'm thankful for multiple layers for protection, but the fabric is so thick that my voice is muffled when I talk and I often have to talk super loud to be heard. When worn as a headband, it's tight enough that it pops off the back of my head. If it had about 1/4 - 1/2" more room, it would be so much more comfortable and still be secure on my face and head.
