The 2025-26 FSV Mainz home shirt by JAKO features a classic red base elevated by an embossed topographic map of the city of Mainz. Refined gold accents highlight the trim and crest as a tribute to the city's "Our Golden Meenz" nickname, while the city's double-wheel coat of arms is placed on the back collar. It provides a distinctly local connection for Die Nullfünfer's campaign in the Bundesliga.
