Fits my 5 yr old perfect! This is my 3rd hat to buy for my kiddos (daughter has one and this is my sons 2nd).
Nice weight/material to keep it on his head if it gets a little windy, and the brim width is just right to keep the sun out of his eyes, off ears and neck, but still allows him to see without blocking his view (some bucket hats are crazy big over kids eyes). Recommended:)
