That one, a baseball cap in the price range should not wash, because the inner part then is the screen made of cardboard, should probably really clear to anyone. So parts are cleaned with either nem Textilerfrischer like Febreze or buys a new one. If you want washable, you have to pay more for the higher quality interior of the screen! :-)
So I'm totally satisfied, and should there ever come off what I order just ne new!
Clear recommendation!
