This is the official third kit for Athletic Club Bilbao, manufactured by Castore for the 2023–24 season. The jersey features a vibrant royal blue base with an intricate geometric sublimated pattern across the body, enhancing visual depth and modern aesthetics. It has a V-neck collar with white trim and red dotted detailing, complemented by short sleeves with subtle white side stripes. The left chest displays the Castore logo (winged 'V' emblem), while the right chest showcases the iconic Athletic Club Bilbao crest—featuring red-and-white vertical stripes, a green tree, and the club’s founding year (1898). Centered on the front is the main sponsor 'Kutxabank' in bold white lettering with black outline and a distinctive red dot on the 'k'. A small Castore authenticity tag appears near the hem. Made from lightweight, breathable performance fabric with moisture-wicking properties, this jersey ensures comfort during matches or casual wear. Ideal for fans supporting the Basque club, it blends sport functionality with contemporary streetwear appeal—perfect for matchdays, training sessions, or everyday casual styling in warm seasons.
