This is the official 2023–24 third football jersey of Bayer 04 Leverkusen, designed and manufactured by Castore. The shirt features a deep navy base with an intricate light-blue line-art city map of Leverkusen printed across the entire front — a distinctive tribute to the club’s hometown. Centered on the chest is the modern circular 'BAYER' wordmark logo in white, while the traditional Bayer Leverkusen crest (featuring '1904' and two lions) sits above it. The collar and sleeve cuffs are trimmed in contrasting light blue, and the right sleeve bears the 'CASTORE SPORTS' branding vertically. A small Castore performance tag appears near the hem. Made from lightweight, moisture-wicking technical fabric, this jersey offers breathability and stretch for optimal on-pitch or casual wear. Ideal for fans seeking authentic club apparel with urban-inspired design, it bridges sportswear functionality and streetwear aesthetics. Perfect for matchdays, casual outings, or as a collector’s piece — especially appealing to supporters who value local identity and contemporary graphics.
