The shirt is the one worn by Beckenbauer in the late 1970s during his time at the club. Maybe there are issues with describing it as a Cosmos shirt. Adidas simply describes it as ‘a direct replica from Franz Beckenbauer's archives’, which pretty much confirms it as the football shirt though.
The slim-fit top has the same detailing as the original, with the v-neck collar, number 6 on the sleeve and chest plus the Beckenbauer name on the back. No club badge, obviously.
