The 2025-26 Osasuna Third Shirt by Macron features an elegant white base enhanced by a raised geometric texture replicating the shape of the club's shield. Paying homage to the club's historic 2006-07 European campaign, the jersey features a V-neck collar, red inserts separating the sleeves from the body, and striking navy blue and red details on the trim, sleeves, and sides. A 3D thermoplastic club crest sits centrally on the chest framed by fine red and blue lines, while a dark blue embroidered emblem of the Autonomous Community of Navarre highlights the outer rear collar. Crafted from breathable, sustainable Eco Fabric, this commemorative kit seamlessly combines modern performance with rich club heritage.
