Wave the flag for one of Scotland's loudest exports with the Biffy Clyro Biffy Fucking Clyro T-Shirt — officially licensed Biffy Clyro merchandise in black soft-style cotton, featuring the band's most uncompromising bit of self-branding.

The Kilmarnock trio (brothers James and Ben Johnston with Simon Neil out front) have built one of British rock's most loved discographies, from Blackened Sky in 2002 through the festival-headlining run of Puzzle, Only Revolutions, Opposites and Ellipsis. "Biffy Fucking Clyro" is the shouted refrain that fans have chanted back at the band for years; pulling it onto a tee is exactly the kind of fan-deep gesture the band rewards.

Cut to a comfortable unisex fit, this short-sleeved tee is a flag for Mon-the-Biff lifers.
