Women’s Athletic Club de Bilbao 26/27 Third Jersey (Customizable)

Created in partnership with Castore, the new collection features white lines inspired by the slats of the San Mamés roof.

Athletic Club and Castore present the third kit the Lions will wear during the 2026/27 season, together with the accompanying goalkeeper shirts.

The main kit, in sky blue and made from AerTek fabric, places San Mamés in a symbolic, limitless sky. Against the predominantly blue background, the shirt features pairs of diagonal and horizontal white lines inspired by the slats of the stadium roof.
