This is a commemorative limited-edition football jersey honoring Basque artist Eduardo Chillida (1924–2002), released by Real Sociedad in collaboration with Macron. The jersey features a bold two-tone design: royal blue upper body with white lower half, separated by an abstract geometric line motif inspired by Chillida’s sculptural forms. Prominently displayed on the chest is the 'YASUDA group' sponsor logo alongside the club crest and a special embroidered patch depicting Chillida’s iconic 'Elogio del Horizonte' sculpture with a crown—symbolizing the club’s heritage and artistic legacy. The left chest bears Macron’s V-shaped logo, while the inner collar includes engraved text: 'Eduardo Chillida 10/01/1924–19/08/2002 Limited edition'. Made from lightweight, moisture-wicking performance fabric, it offers breathability and comfort for casual wear or fan display. Ideal for football supporters, art enthusiasts, and streetwear collectors seeking culturally significant sportswear. The jersey blends athletic functionality with high-concept design, reflecting Real Sociedad’s deep ties to Basque identity and modern cultural patronage.
