A small breather that fits snugly into a Jedi Knight's utility belt, the A99 aquata breather is a compact mouthpiece designed to supply its wearer with a breathable gas. The A99 has advanced filters to allow it to function underwater, in a vacuum, and in certain poisonous environments. The A99 has a number of variants to accommodate a variety of alien physiologies. The A99's miniature compressed air tanks can supply two hours of oxygen.
