Product sizing would have been helpful. Too small
"Ordered this for my 12 yo. Arrived for his birthday and doesn't fit! Checked in case I made an error in ordering, but the product does not list a size at all and the hat states 53cm. Why this couldn't have been listed on the website, and I would have to return at my expense! Product listed has 'onesize', meaning it should cover an average sized head from the age of 8-16. Barely would have fit my 5yo."
