parolon

Parolon is a fictional material that appears in the science fiction novel "Dune" by Frank Herbert. It is described as a synthetic, porous, and exceptionally strong fabric used primarily for the creation of stillsuits. Stillsuits are essential survival gear for the Fremen, the native inhabitants of the desert planet Arrakis, as they allow the wearer to recycle nearly all bodily moisture. The material's unique properties of breathability and liquid absorption are crucial to the stillsuit's function. Parolon is depicted as being resistant to the harsh environmental conditions of Arrakis, including sandstorms and extreme temperatures. Its development represents a significant technological advancement within the Dune universe, enabling life in an otherwise uninhabitable environment. The exact composition and manufacturing process of parolon are not detailed in the novel, but its importance to the survival of the Fremen is consistently emphasized. It is one of several specialized materials developed to adapt to the challenges of Arrakis.
