The [b]stillsuit[/b] is a special suit that first appeared in the [[science fiction]] novel [i][[dune_(series)|Dune]][/i] from 1965. It was created and is used by the [[Fremen]] who live in the [[desert]] [[planet]] Arrakis.

It is a special [[bodysuit|body-enclosing suit]] designed to collect and recycle all the moisture the body releases, from urine, feces and sweat, to the exhalation of [[water]] vapor in the breath.

The special fabric of the suit is a micro-sandwich designed to dissipate heat and filter wastes while reclaiming moisture. The water is then held in catchpockets and made available to drink through a tube.

A Fremen in a well-kept suit can survive weeks in the desert without any other source of water.
