The cap was a good fit on my four year old, however, her hair did get a bit wet.

My daughter did not like this cap. She said it was too thick and pulled her hair more than her regular caps. It was also cut small.

these swim caps are okay, but too small for kids that are over age 5, especially girls who have more hair to cover. We bought them for a children's swim party, and found about half were too small for the 10 year olds.  Good quality though for those it fit.

One size really does fit all! Using it 3 times a week and still loving it.

Very small.. My 8 year old wears this, I bought it for my 10 year old, almost 11 year old and well it was to small.. It is heavy so it does not slip as easy and I think it is going to sustain the chlorine longer than the rest! Maybe even Speedo! They don't pull there hair like the others either! You can not beat the prices here! We have bought tons of these caps and the kids love the ones from here the best! I have actually bought some at swim shops that were not Speedo and paid a lot to find they have actually bleached in spots due to the  kids leaving them in there bags over night.

My 9, nearly 10 year old son loves these caps.  He used to always complain about the regular size caps(any brand) letting water in his caps.  He said these go on easily & give a nice snug fit.
