So is the whole suit rubber again?
I wonder if it wouldn't be much better and not that costly to make this suit in some spandex type fabric and attach the armour pieces to it.
Not sure how the retooling works, but it almost looked like the shoulder pads were a loose piece of like hard plastic or something on the prototype, allowing more shoulder movement.
As for cost, I imagine a more true to the film construction method would have padded like another $20 or more onto what we pay, it's $150 for the rubber suit.
