This is a very nice product but too small for my 5 and 8 year old grand-daughters. They do have large heads, which I should have remembered, but these would not fit at all, even on the 5 year old. They do have an elastic in the back to give some lee-way but still didn't fit. I would order the adult size unless they are for small heads. They can grow into them. I plan to give these two-year-old twins.
