Athletic Club and Castore have officially unveiled the club’s new third kit for the 2026-2027 season.
The garment pays direct tribute to the architectural beauty of the iconic San Mamés stadium.
Castore’s new 26-27 Athletic Bilbao third shirt comes in a striking sky blue as the main base color, alongside white graphic elements across the shirt.
Black details are used on the Castore logo on the right chest, the main sponsor "Kutxabank," the back sponsor "DIGI," and the trim around the round collar.
