Survival armor was a type of spacesuit commonly used among both large corporations and independent spacers. Zero-G workers for the Tagge Mining Company wore survival armor, and Han Solo kept at least one such suit aboard the Millennium Falcon. The suits were equipped with a jetpack.
Luke Skywalker used Han's survival armor to infiltrate a group of Tagge workers and learn of the plans to destroy the Rebel fleet using Omega Frost. Luke later wore the suit when he escaped a Mining Explorer in a TIE fighter eventually abandoning the small craft via ejector seat before it crashed into an asteroid. In the suit, Luke reached an asteroid where he was able to destroy a conductor tower and disable Omega Frost.
