The 2026-27 Cardiff City home shirt marks the debut of Castore as the club's technical partner, delivering a design that combines tradition with clean, modern details. The jersey features the club's iconic royal blue as its primary base color, paired with crisp white accents. Distinctive white triangular panel inserts frame the crew-neck collar at the shoulders, complemented by matching white trim detailing the sleeve cuffs. A personalized, heritage-inspired touch is located on the upper back of the neck, featuring a small printed Welsh dragon emblem positioned directly above the club's founding year, 1899.
