This is the official 2023–24 home football jersey of CA Osasuna, produced by Adidas. The vibrant red jersey features a subtle horizontal ribbed texture for enhanced breathability and aerodynamic performance. Navy blue trim accents the crew neck collar, shoulder stripes, and side panels, adding contrast and visual structure. The club’s crest—featuring a crowned shield with 'C.A.O.' initials—is prominently displayed on the left chest, while the Adidas three-stripe logo appears in navy on the right chest. The front showcases the main sponsor 'Kosner' in bold white lettering, with the tagline 'Climatizacion eficiente' beneath it. The left sleeve bears the LaLiga patch ('CE LIO'), and the right sleeve includes a small white number/identifier patch (likely player or size marker). Made with Adidas AEROREADY moisture-wicking technology (visible at hem), this lightweight polyester jersey ensures optimal comfort during matches or casual wear. Ideal for fans supporting Osasuna at El Sadar Stadium or daily sporty streetwear styling in warm seasons.
