The 2026-27 Kaiserslautern home shirt by Castore introduces a bespoke and modern look for the 2. Bundesliga club. The jersey is predominantly red, featuring an intricate, all-over graphic pattern across the front that incorporates "Red Devil" motifs such as a devil's head, trident, scratch marks, and tail, alongside the words "Betze" and "Lautre." Striking white shoulder panels provide a bold contrast to the red base, while the collar and sleeve cuffs are detailed in classic red and white. The plain red back features a special logo on the upper back celebrating the 750th anniversary of the city of Kaiserslautern, and the traditional devil's head emblem is placed inside the collar.
