Celtic's 2017/18 home shirt, made by New Balance, stays true to the vertical green and white hoops the club has worn in some form since the late 1800s. There's little room, or appetite, for reinvention here. New Balance's approach is restrained: a simple collar, subtle fabric texture, and a clean overall look that respects the template without feeling stale. For collectors, it's a reliable entry from a period of aesthetic consistency, where the shirt's identity was always going to be defined by the stripes rather than the maker.
