Slip on the Green Day Sweatshirt: Cat Blaster in grey cotton — officially licensed Green Day merchandise carrying the Cat Blaster cartoon graphic.

Cat Blaster sits in Green Day's longer line of cartoon-mischief artwork, the same anarchic register the band has paired with its logo across decades of pop-punk records. The illustration leans into the band's irreverent sleeve-and-merch tradition rather than the cleaner stadium-rock typography of later eras.

Grey cotton sweatshirt with long sleeves, crew-neck pullover, no hood, no zip. Sizes run from X-Small through XX-Large.
