The supertight one is the Test Match version, the most expensive. Then you have PRO jersey (The second picture) and the classic.
I have many PRO and Test Matches but I haven't a Classic version. So I need to know the differences between the PRO and the Classic. The size chart says that they are equal but as the materials are different I'm not sure about it.
The PRO version is tight on the slevees but loose on the body. The Test Match version is supertight everywhere and I don't know about the classic. Looks like loose everywhere.
