This is the official Athletic Club Bilbao 2023–24 third football jersey, manufactured by Macron. The shirt features a vibrant royal blue base with an intricate all-over geometric pattern in tonal shades of blue for visual depth and modern sportswear aesthetics. A V-neck collar with white trim and red dotted stitching adds refined contrast, while the club’s iconic shield crest—featuring red-and-white vertical stripes, green laurel branches, and 'ATHLETIC CLUB BILBAO' text—is prominently displayed on the left chest. The front showcases the main sponsor 'Kutxabank' in bold white lettering with black outline, reflecting the club’s long-standing regional banking partnership. On the right sleeve, the LaLiga patch (B2B PA) confirms its authenticity for official league play. Made from lightweight, moisture-wicking performance fabric, it ensures breathability and comfort during training or matchdays. Ideal for fans seeking authentic supporter wear or casual streetwear with strong Basque identity, this jersey blends heritage pride with contemporary design. Perfect for matchdays, casual outings, or layering in transitional seasons.
