Celtic's 2025/26 home shirt, made by Adidas, returns to the vertical green and white hoops that have defined the club since 1903. Few clubs in European football have maintained a single visual identity with such consistency, the hoops are not a throwback, they are simply what Celtic wear. Adidas, back at the club since 2020 after a long absence, works within tight visual constraints here, which makes the smaller details, cut, collar, finishing, the real points of interest for the serious collector.
