Athletic Bilbao Away Jersey 2026/27

The Athletic Bilbao Away Jersey 2026/27 features a predominantly black design with distinctive red detailing.

The black shirt is paired with red shorts and red socks, creating a powerful alternative matchday look that remains closely connected to Athletic Club's traditional red-and-white identity.

The official Athletic Club store lists the men's Away Pro shirt in Black and confirms the Castore branding and technical construction.

Castore Athletic Bilbao Away Jersey

The 2026/27 Athletic Bilbao away shirt is designed by Castore, Athletic Club's official technical partner.

Athletic Club officially launched the new away kit on June 10, 2026, confirming the partnership with Castore and making the kit available through the club's official physical and online stores.

The Castore logo appears on the chest alongside the Athletic Club crest.

Athletic Bilbao Black Away Jersey

Black is the defining colour of the 2026/27 away shirt.

The dark base creates a modern and understated appearance, while red details provide a strong connection with the club's iconic colours.

The combination of black, red and white creates a distinctive Athletic Bilbao football-shirt style suitable for both matchdays and everyday football fashion.

“Where It All Began” Athletic Bilbao Jersey

The concept behind the 2026/27 away kit is “Where It All Began.”

Athletic Club explains that football begins in the places where players take their first steps: streets, playgrounds, beaches and local pitches.

The kit celebrates these early experiences and the emotional connection they create between generations of Athletic Club supporters.

The central idea is that football is more than a stadium or a match—it is a feeling that begins long before professional football.

Athletic Club Heritage Away Shirt

The 2026/27 away jersey focuses on the relationship between the club's past and present.

The official campaign emphasizes how the same passion is passed from parents to children and from one generation to the next.

This heritage concept makes the shirt particularly appealing to Athleticzale supporters who value Athletic Club's unique football culture.

Athletic Bilbao AerTek Football Jersey

The official Athletic Club store lists the men's Away Pro shirt with AerTek technical fabric.

The shirt is designed as a performance football jersey while maintaining the lightweight feel and technical construction expected from a modern match shirt.

The AerTek branding can be seen on the lower part of the shirt.

Athletic Bilbao Black and Red Away Kit

The complete 2026/27 Athletic Bilbao away kit combines:

• Black away jersey
• Red football shorts
• Red football socks

Athletic Club officially describes the away uniform as a black shirt combined with red shorts and socks.

This colour combination creates a strong visual contrast with the club's traditional red-and-white home kit.
