Microcase

Microcases, also spelled "micro-cases" and called "micro-packs" were large cases that could be carried on the back of an adult male Human.

Luke Skywalker hid Biggs and Windy, Leia's two brothers, in hollowed out microcases, and put them into hibernation using a power pack from Kane Starkiller's chest cavity.

The shell of the microcase resisted scanners, making it easier for Luke to get his companions to safety in them.
