How about these?
Have bought these hats for both of my girls and they are by far the best kids sun hats. No other brand makes an extra wide brim like these. The string is long but I just cut it and easily bought a clasp off of amazon. Please make these in bigger sizes!!! My daughter has almost out grown the ML and I want to keep buying them!
I would give this hat a five star rating if there was an adjustable clasp or draw string instead of just very long strings that you have to tie up under the chin... I'm not going to lie I was disappointed. But the brim is perfectly oversized and the pattern and colors are very cute and exactly as pictured.
