[Source] The EMS-90 Bubble Cloak was a self-contained survival unit. It allowed a being to have emergency protection against the vacuum of space without having to carry a bulky EVA pod. It appeared to be a thick but fashionable cloak but upon activation it would fan out to enclose the wearer in a 1.2 meter diameter survival bubble. It carried a 2-hour supply of air and would protect the occupant from the freezing cold of space.
