Athletic Club have unveiled their 2025–26 home kit in collaboration with Castore.
The release commemorates the centenary of the bust of Pichichi being placed at San Mamés in December 1926, a tradition that gave rise to the floral tribute presented by visiting teams during their first official match at the stadium.
This year’s shirt continues that ritual by incorporating a symbol rooted in Basque heritage; the Eguzkilore, a flower associated with protection and resilience in Basque mythology. It appears on the upper back of the shirt, representing a modern extension of the tribute to Pichichi.
The kit features the club’s classic red and white stripes, a black polo collar with red and white trim, and matching sleeve cuffs. The Castore logo and main sponsor Kutxabank appear on the chest, while women's team versions feature Kosner branding. The badge is silicone on the Pro edition and embroidered on the Replica.
Created from breathable Aertex fabric, the kit is completed with black shorts and red-white-accented socks.
