With this being a rigid suit with normal air gas mixture, are divers still susceptible to decompression sickness? Is the pressure inside the suit the same as sea-level ambient, or is it higher to reduce the strain on the suit? On a different note: can we please, pretty please, stop calling every form of suit 'Iron Man-like'? Aside from being made of metal, this bears almost no resemblance.
