Athletic Club Training Shirts

Official Athletic Club training shirts

On this page, you'll find only official Athletic Club training shirts. These are the newest models from the 2024/2025 season, supplied by Castore, the official kit sponsor of Athletic Club Bilbao. All shirts on this page are approved by the club and identical to the ones worn by the players during training. You're always ordering an authentic product that is accurate in every detail.

The collection is designed to let you train, play sports or support your favorite club in style and comfort. Each training shirt proudly features the Athletic Club Bilbao crest and is styled in the signature colors of the new season. Many fans also choose to wear these shirts off the pitch as a stylish and practical way to show their love for the club.

Available sizes and fit

All Athletic Club training shirts are available in a wide range of adult and kids' sizes, from XS to XL. For each model, it's important to consider the fit. The current Castore training shirts fit quite slim. For a looser fit, we recommend ordering one size up.

Want a form-fitting shirt like the players wear? Then it's best to choose your regular size. Unsure between two sizes? Check the size chart available with each product. It will help you make the right choice so you can be sure the shirt fits comfortably while training or cheering.

The Athletic Club training shirts from the 2024/2025 season combine style and functionality. Castore uses lightweight and fast-drying materials suited for intense training sessions. The fabric wicks away sweat quickly and helps your body stay cool, even during hot or heavy workouts.

The shirts feature a modern look with sharp lines, club details and subtle color variations that match the season. The Athletic Club crest is embroidered and the Castore brand logo appears on the chest. The back often includes ventilation zones for better breathing.
