This authentic retro football jersey features a bold black base with vibrant lime-green diamond (harlequin) pattern across the front and sleeves, evoking iconic 1990s Spanish football aesthetics. The shirt is crafted from lightweight, breathable polyester performance fabric with a classic polo collar in black, accented by green inner lining. Prominently displayed on the left chest is the official Real Racing Club Santander crest — circular with crown, green-and-white stripes, and 'REAL RACING CLUB SANTANDER' text. A gold-embossed commemorative patch appears near the hem, reinforcing its heritage design. The inner neck label reads 'quatro POMPEI', identifying the manufacturer (a known Spanish sportswear brand active in the 1980s–90s). Short sleeves with ribbed cuffs ensure comfort and mobility. Ideal for fans of vintage football culture, streetwear collectors, or casual wear with nostalgic flair — pairs effortlessly with jeans, shorts, or layered under denim jackets. Perfect for summer days, matchdays, or urban styling, this piece blends sport heritage with contemporary fashion sensibility while honoring Cantabrian football tradition.
