The 2025-26 Spezia Third Shirt features a rich golden base inspired by the maritime heritage of the Cinque Terre. Designed by Kappa, the jersey incorporates black and white detailing on the collar, cuffs, and crest, creating a consistent identity with the club's traditional colors. The design draws specific inspiration from seafaring life, featuring graphics that reference ropes and nautical knots to symbolize the deep roots and authentic spirit of the local community in Vernazza.
