A red full-body suit that renders its wearer invisible, used by Starfleet and Son'a observers secretly studying the Ba'ku village in Star Trek: Insurrection.
An isolation suit is a hooded, full-body garment that hides the person wearing it from view, allowing survey teams to walk among a population without being noticed. It appears in the 1998 film Star Trek: Insurrection.
In 2375 a joint Federation and Son'a team uses the suits, together with a concealed duck blind, to observe the Ba'ku, who are believed to be a pre-warp people. The mission collapses when Data, damaged by Son'a weapons fire, pulls off his headgear in the middle of the village and then exposes the hidden observation post, revealing the whole operation to the startled Ba'ku.
The incident brings the Enterprise-E to the planet and leads Picard to uncover the plan to remove the Ba'ku from their home by force.
