The robes used by the Narth contain a subspace pocket in their left sleeve, with the only limit in what they can contain being what can fit though the subspace hole. Not much else is known except only the Narth wearing a particular robe can move objects into and out of the pocket associated with that robe.
Seenian Battle suits normally contain two subspace pockets - one containing a Casern with Seenian Battle Robots, and the second one with a lot of food, water and energy.
Notes were found at a Seenian depot that indicate studies had started on using subspace pockets to greatly increase the range and ammunition on warships. It is unknown the result of those studies.
