Stillsuit
The Fremen body suit that reclaims the wearer's own moisture.
A stillsuit is a fictional body suit in Frank Herbert's Dune universe, worn by the Fremen of Arrakis. The Terminology of the Imperium describes it as a body-enclosing garment of Fremen design that dissipates heat, filters bodily wastes and retains and reclaims moisture. In Dune, Imperial Planetologist Liet-Kynes explains the suit, which cuts the body's water loss to a few millilitres a day; because water is so scarce on Arrakis, its preservation is sacred to the Fremen.
Lore & Background
In his essay Stillsuit in The Science of Dune (2007), John C. Smith examines whether the suit could work as described and concludes that a strictly literal design probably would not and would most likely cook the wearer, though engineering solutions can be envisioned. In Dune (2021) Chani and Stilgar are shown wearing stillsuits.
