^^ like he says
But the home authentic doesn't say climacool. The black authentic feels exactly like the replica version, whereas the home authentic's material is finer.
i think it all depends from where the jersey is manufactured.
I have a few Adidas player issues and some say Climacool on the neck, as well as some without any Climacool logo on it.
Some sizing are in lettered like S,M,L,XL and some i have are in number sizes.
