Athletic unveil new 2026/27 warm-up shirt with red and black design | OneFootball

Athletic have officially unveiled their new warm-up shirt for 2026/27, first shown on the San Lorenzo pitch in Laredo before the friendly against Racing de Santander on Tuesday.

The club said the top combines functionality with a distinctly sporting look. Designed by British technical brand Castore, it features jagged red and black stripes that recall the tradition of teams such as Milan.

Supporters quickly noticed players completing pre-match drills in the new red and black colours, a clear break from the usual routine before kick-off.

With the classic red and white home, an all-black second and a sky-blue third already revealed, this was the final piece of the Castore-designed matchday range.

The collection also includes a black sweatshirt with red shoulder detailing, and it is on sale now in club shops and on the club’s online store.
