This is the official 2023–24 home football jersey of Racing Club de Lens (RCL), a French Ligue 1 club, produced in collaboration with sponsor Auchan. The jersey features bold vertical stripes in black and vibrant green, with intricate geometric patterns woven into the green panels—inspired by regional Picardie motifs, reflecting the club’s cultural heritage. A large white 'Auchan' sponsor logo with its signature bird emblem dominates the chest, while the RCL crest (red shield with 'RCL' and a lighthouse) sits on the left breast, commemorating the club’s 120th anniversary (‘120 ans’ text above). The collar is black with a subtle inner tag reading ‘COOCH’—likely the manufacturer (Coq Sportif or local supplier). Short sleeves have green underarm panels for breathability, and a small gold ‘PROTEC’ authenticity patch appears on the lower left hem. Made from lightweight, moisture-wicking polyester fabric (likely with ‘DRYCELL’ tech noted near hem), it offers optimal performance for matchdays and fan wear. Ideal for match attendance, casual streetwear, or sports training in warm seasons. The design balances tradition and modernity, appealing to loyal supporters and fashion-forward football fans alike.
