A passive survival suit for enabling a diver in a confined bell to maintain body temperature for at least a minimum interval in the event of failure of external thermal sources uses a combination of thermal insulation and a coacting breathing gas regenerator and scrubber system. The thermal insulation comprises a combination of a hooded sleeveless vest and a body shell, each of which provide a long heat conduction path length and minimum internal heat convection currents. The regenerator and scrubber system are arranged such that thermal energy in expired breathing gases is stored with high efficiency and used to heat breathing gas during intake, while the carbon dioxide scrubbing reaction is carried out in an optimal warm, moist atmosphere and contributes heat to aid in maintaining the diver's temperature.
