Thumbs up!

This mask was a big hit. I bought it as a gift for a coworker who is an 8th-grade math teacher. She absolutely loved it.

Great quality

I've bought 6 masks and found them all to be of great quality and fit nicely. I've given a couple of them as gifts as well and the recipients are also happy with them.

Great mask....almost perfect

I love that these masks are 3 layer cotton with an area for filters. The youth size fits my average size 8 year old really well. My only complaint is that I wish they had a bead (or even a knot) on the ear loop to prevent the slider from coming off.
