They fit my 2 year old son perfectly. Unfortunately it is very difficult to find 3x5 masks but they are better than another 3x5 brand I have. They are soft and not itchy where the ear loop connects to the mask (like the others I got from the Dif company). My little son is 2 years old and we don't have to tie a rubber band all over the place to make it fit better, it just fits! They also don't smell the same as I've seen in other mask reviews. I would definitely recommend it. I just wish I could buy a bigger pack.
