On the wild planet of Mimban, Luke Skywalker and Leia Organa employed thermal capes as both coverings and protection from the elements. A thermal cape, which is sometimes referred to as a "thermal wrap," functioned as a poncho designed to help the individual wearing it maintain their core temperature in frigid environments; these were generally standard issue in most survival kits.
Beyond its use as wearable attire, a thermal cape could serve as a makeshift blanket or a temporary form of refuge. The construction of thermal capes often involved a blend of alcomase combined with the silk produced by the Vectinian spider.
