I think it's great to have these options for very young kids who still need to be able to mask in some situations. I was hopeful these would be the right choice for my 2.5 year old, who has too small a face for the Posh masks her older siblings wear. Unfortunately, she didn't like the way they fit and won't wear them. We've gone with a different "boat" style mask more similar to the Posh ones for her, but we've donated these to a local preschool and I'm sure there will be some kids there that they are perfect for. They are definitely best for very young kids. I would say ages 2-4 are most likely to fit. My 6yo and 8yo have fairly small faces but these were way too small for them. Extending the ear loops didn't help because it was the actual mask itself that was too small. So definitely only buy for younger children.
