These are very comfortable face masks; however, they run a bit large and are a little too big for me (and I am not a small person). They do fit my husband's big head. So if you have a big head, they're great. I shortened the ear loops by 1/2" and now they fit me and don't slide down.These are super thin and thus not likely very protective. But, my kids love them and they fit well. In my opinion they’re good for when you’re physically active or it’s very warm out (we are in Texas) because they don’t feel thick on your face. But if you can tolerate a thicker, more protective mask, I’d opt for that whenever possible.Comfort is excellent. Life of these, even with washing by hand- not the best. They are great for “style fun” but after washed 2xs, no longer stay up. Will need a nose secure piece placed. I can do this because i Have tools; not everyone does.I ordered these for my 9 year old son. He has asthma so I was slightly worried about the affects of him wearing a mask all day at school. There has been zero complaints from him, in fact he has actually told me he really likes then and having the variety of colors is a. Great plus..I bought these for my kids to wear for school. Its a great product. Easy to wash and durable material. My kids like them and love the variety of colorsThese masks fit my 9 year old so well that we ordered another set. He has a hard time with a lot of materials irritating his skin and not fitting right for masks. He seems to be a little to big for kids size mask but his face is too small for most adult face masks. These fit great and really wash up well. He wears them all day at school and they never bother him. Very happy with these masks.Great for adults but way too big for kids which is why I purchased them. My kids are 7 and they just fall down. It is made of great material and had I purchased them for an adult, I would’ve given it a 5 star!Te permiten respirar lo recomiendo
