Which back protector?

[Psychybikey]

I have an RST jacket which came with arm and shoulder protection but no back armour.

The question is, does the armour have to be specific to the jacket or are back protectors interchangeable? This will be the difference between going to a shop (with the jacket, obviously) and trying one in the jacket, or getting it straight from RST and knowing it will fit.

Thanks.

I'm lead to believe this back protector will fit most RST jackets which have a back protector pocket.
