Just got the cowboy hat (shipped very fast) and it is beyond my imagining!  It's hard felt, like a grownup's hat, and is definitely one-size-fits all.  Inside the crown is a stretchy headband that will make the hat fit my three year old grandson and will probably continue to fit him for several years.  The hat looks great, feels great and is incredible value for the money.  This will no doubt be passed down to my younger granddaughter at some point when her brother is ready to let go of it.  He's going to be one happy little cowboy this Halloween!
