It doesnt flop down over eyes! I bought size large for six year old. It is an excellent hat for playing in the sand, ocean, and sound. It is great for kayaking and boating! It is adjustable around and also has chin cord. The chief complaint before this hat was that previous hats all flopped down in the eyes and this one does not. It also stays in place in all conditions even going high speeds on the boat. Six year old does not complain about this hat and doesnt have to be reminded to put it in before going out! Its a miracle hat! I highly recommend it.
