Ring-Suits
Description: imagine a spacesuit made up of a series of snug but not skin-tight blue-grey-green rings that resemble hardened ooze. Bits of metal and plastic are interspersed at various joints.
These biological spacesuits are perhaps a bit physically unaesthetic, but Ring-Suits are the gear of choice for anybody mining a planetary system’s Oort Cloud. They’re ‘biological’ entities that originated on comets: a ‘wild’ Ring can function in a temperature range of just above absolute zero to about 120 degrees Fahrenheit. Above that point, they go into hibernation indefinitely, and can survive temperatures just below that of boiling water. Rings instinctively stack one on top of each other, effectively forming an impenetrable barrier that produces a hollow internal space that can be slowly warmed via waste heat (which the Rings then use to maintain life functions).
