For reference - I bought a pair of Size 58 Vancouver 2010 authentic jerseys. A friend who is 6'5", 230 lbs put it on, and it pretty much just fit him. The best comparison to that is probably a Size 52 authentic jersey, pre-Swift.
The 62s that the Canadian team wore in Vancouver would probably be about the same as a 56, pre-Swift jersey, which is basically the standard size for hockey players these days - XXL. On the previous generation, that's what a 64 likely was.
