The 2025-26 Osasuna Home Shirt by Macron pays tribute to the 40th anniversary of the club's European debut in 1985. The jersey features the traditional Navarra red base with an elegant vertical pinstripe effect and a custom V-neck collar. Dark navy blue graphic patterns on the shoulders add character, while a commemorative gold patch on the front and an inscription of past European appearances on the reverse hem complete the historic design.
