Pull on California pop-punk with the Green Day T-Shirt: Green Mask, an officially licensed black cotton tee printed with the band's defiant masked-skull imagery.

Green Day formed in East Bay California in 1987 with Billie Joe Armstrong, Mike Dirnt and Tré Cool, and broke into the mainstream with 1994's Dookie. The band's later American Idiot (2004) and 21st Century Breakdown (2009) cycles leaned hard on red-and-black political-punk imagery, and the Green Mask design slots into that wider visual catalogue.

Available in a black colourway, the shirt prints clean on cotton for daily wear or gig nights.
