A protective suit has a supply of breathing air and includes a multiplicity of hollow chambers covering the body of the wearer which can be filled with breathing gas. The interiors of these chambers communicate with one another. The protective suit also includes hollow bodies which rest against the head, neck and upper torso region of a protective helmet portion. The interiors of these bodies communicate with those of the hollow chambers and with the interior of the protective helmet portion. The protective suit is configured for use for divers such that it is suitable not only for providing a sufficient volume for the supply of breathing gas and for thermal insulation but also, when it is filled, of first quickly pushing the diver up to the surface of the water and of providing a safe position of repose of the diver after ascent in which he can breathe freely, once he has reached the surface of the water. For this purpose, a source of breathing gas is connected to the hollow bodies and the connection between the hollow bodies and the hollow chambers is provided by a pretensioned transition element. In addition, the hollow chambers have an outlet which communicates with the interior of the protective helmet via a further pretensioned transition element. The opening pressure of the first-mentioned transition element is less than the opening pressure of the second-mentioned transition element.
