Stitch on Green Day Back Patch: Kerplunk — officially licensed multicolour woven Green Day merch reproducing the Kerplunk sleeve as a large back-panel patch in 95% cotton, 5% polyester.

Kerplunk is one of the touchstones of Green Day's Lookout! Records era, and rendered at back-patch scale the design has room to breathe: cover motif reproduced in tight woven stitch, the colourwork holding shape after repeated washes. A statement piece for a battle jacket rather than a subtle badge.

The patch is a large woven cotton-blend panel with a plain reverse for sew-on attachment to denim, canvas or a leather cut. Colour reads across the design in tight stitch. Standard Rockoff back-patch construction, the collector value sits in the reproduction quality.
