7. Outer Atmospheric Armour
Introduced to the world in Iron Man’s mission to retrieve his stolen prototypes (see #8), the Atmospheric Armour is like the logical progression of the Space Armour, with a far more unique design. It is designed not for heavy combat, but for speed and subterfuge, and is a good deal lighter than his classic suits for the ease of making the ascent into space.
As a side-effect of this lightweight frame, however, the suit lacks the protection of some of the heavier-duty armours on this list. It would have trouble withstanding an assault by Stark’s own technology, which, unfortunately, seems to be what most of Iron Man’s foes tend to be equipped with.
