Guinness “flat cap” or “paddy cap”. I have also heard people call it an “Irish hat”. Guinness logo is on the back of hat. Awesome plaid design with the colors white, yellow, and green in it. Took pic of tag on the inside of hat. Has a button on the front if you want to unbutton (see pic). No rips, tears, or stains. Comes from a smoke free and pet free home. The only thing I don’t know is the size. It doesn’t say anywhere. This thing just sits in my closet, so I am looking to sell!
