That was meI think that it's just a first draft, the Mazda logo looks far too big. A North supporter on the FJGD board posted pics of the back, where it says 400 on top of each stripe, and the collar is blue.
These are straight from the rooshop, not sure why the collars are different from this to what Boomers wearing though, pretty sure something similar went on with the indigenous jumper on the store though, something about a logo not being there or whatever.
