My daughter (2.5 years old, 22lbs) has a very small face with round cheeks so finding something that is comfortable, secure, and without gaps has been next to impossible. Every mask I found would move upwards and poke her in the eye. Additionally, I knew how annoyed I can get with a mask rubbing against my nose and wanted a "tent" feature for her (Especially with the constant runny toddler nose). She had a mask aversion until I found these and now she loves them and asks for them. Wow. We will never use anything else! Worth every penny.
