Reviewers are saying that this hat is made in China. The one I received has a tag on the inside that says Interstellar Propeller, 1600 Woolsey St, Berkeley, CA 94703 415-648-9727. The tag under it has an imprint of a US Flag with "Made in the U.S.A." printed in blue ink. The hat is extremely well made and I will wear it proudly. I'm 63 years young and will have a lot of fun with it!
