These breathing valve masked were exactly what I was looking for. I do have a variety of them but I am very picky about my variety. I have had these a few months and they are among my favorite. The colors on them are vibrant and they pop for me. I do love the fact that they are unisex, so my husband has one as well. They also come with dust covers or filters which ever you want to call them. So you have your extra protection for those small particles floating into your mask. I think they were well designed and fit very well. I think they do exactly what they are supposed to do and they are a great buy.
