Life support

A life support system was a device or group of devices that made the interior of a starship capable of supporting life in the otherwise deadly environmental conditions of space. Some crafts, like the Imperial TIE/ln space superiority starfighter, lacked such systems, which forced their users to wear life support chest pieces with breather tubes connected to the helmet to provide necessary gases.
