This is the new Athletic Bilbao kit 2026/27, Athletic Club’s new home uniform for the upcoming La Liga season. Made by Castore, the new Athletic Bilbao shirt was officially unveiled on May 20, 2026 and will be worn by the club this weekend when they square off against Spanish giants Real Madrid. Atletico Madrid will also be debuting their new black away jersey in the same game week against Villarreal.

The new Athletic home shirt features the club’s traditional red and white stripes (albeit a little thinner) and has a mostly plain red back. The new goalkeeper top is a dark grey creation from the Castore stable.
