This is an official Olympique de Marseille training jersey, featuring a modern performance design with technical fabric for breathability and moisture-wicking. The jersey showcases a bold black base with contrasting light blue side panels and collar trim, creating a dynamic two-tone aesthetic. A distinctive vertical pattern of fine white dots runs down the center front, enhancing visual depth and sporty sophistication. Prominently displayed across the chest is the 'CMA CGM' sponsor logo in large white lettering, while the club’s iconic OM crest—featuring the intertwined 'O' and 'M' with a star above and the motto 'Droit Au But' beneath—is positioned centrally above the sponsor. The inner neck tag includes size and care information, and a small 'Dri-FIT' or similar performance tech label appears near the hem (likely Nike Dri-FIT, though not fully legible). Designed for athletic training sessions, this jersey combines club identity with functional sportswear engineering. Ideal for fans seeking authentic matchday-adjacent apparel or active wear with strong football heritage. Perfect for casual streetwear styling in summer or mild weather due to its lightweight, breathable construction.
