I read the reviews first before ordering and since people were commenting that it was small, I sized up...way up. I ordered the teen/adult size for my 8 year old who is the in 75th percentile for weight and height. When the hat arrived, it was ... TOO SMALL! Either the company made a mistake in labeling or the models used for making hats live in a land of people with extraordinarily small heads. I wish I could give it five stars since my son loved the style and warmth of the hat, but it was just too small that I couldn't keep it. Too bad...please make the hat much, much bigger!! If this is the adult size, I can't imagine how tiny the small size must be! So for context, I included two photos of the TEEN/ADULT size - it fits my son's teddy bear. It also fits a standard size tissue box, so you can imagine how small it is.
