The 2023-24 Athletic Bilbao Authentic GK Home Shirt features a classic black base with white vertical stripes and graphics inspired by the exterior of the San Mames stadium. This historic season saw Los Leones triumph in the Copa del Rey to secure their first major trophy in forty years while achieving a strong fifth-place finish in La Liga. It is a sophisticated piece that commemorates the club's 125th anniversary and their successful return to European qualification.
