Abstract: This invention is an integrated anthropomorphic g-suit, with a breathing regulator and means for protecting the user of the suit from hostile environments. The suit has a flexible, distensible, impermeable inner liner that conforms to a user's body, and a flexible, impermeable, nondistensible outer liner that fits over the inner liner, to trap a thin layer of fluid between the inner and outer liners. The suit acts a tank of fluid, so that the suit exerts a hydrostatic pressure on the user's body, preventing blood from draining from the user's head, when the user is subjected to acceleration. Chemical, radiation and biological protection is provided by the fluid, which circulates through a heat exchanger incorporated into the suit. The user is supplied with a breathing system having a regulator that is responsive to the pressure of the fluid in the suit, such that the pressure of the breathing gases being supplied to the user is approximately the same as the fluid pressure in the thoracic region of the suit. The regulator can vary the pressure of the breathing gas, automatically as a function of ambient pressure.
