Kiro wearing a water tank on the surface of Iskalon. The term water tank referred to a specialized protective garment utilized by Iskalonians when venturing away from the aquatic environments of their home planet, Iskalon. Contemporary iterations of these suits often consisted of only a helmet capable of water recirculation. However, earlier models were full-body enclosures, heavily reinforced with padding to ensure the suit's integrity. Kiro's improvisation of a water tank during his assignment on Kinooine, achieved by merging a flight helmet with a portable water container, demonstrated their relatively simple design.
