The 2025-26 Osasuna Away Shirt by Macron features a vivid green design that pays tribute to the club's 1991-92 UEFA Cup campaign and the flag of Pamplona. The jersey is detailed with a red polo collar and matching red sleeve cuffs, complemented by a subtle diagonal embossed pattern across the front. Additional features include a silicone-applied club crest, the Navarra crest on the back of the neck, and a customized back hem listing the team's major European appearances.
