This is a Sense of Wonder hat. It's made of soft, comfortable cotton fabric. It has a chin strap, so you don't have to worry about it blowing away. It's also reversible. The tag has been removed, so there's no size information, but it was worn a few times when the child was 1-2 years old. There are no noticeable stains or scratches, but please understand that this is a used item before purchasing. Thank you.
