Abstract: A heat resistant suit includes an inner garment designed to circulate cooling air against the wearer's body. The inner garment is connected to the cool air output of a vortex carried in a pocket in an outer, heat reflective coverall. A safety bottle is carried in another pocket of the coverall, with the safety bottle connected to a pressure valve which is also connected to an external source of breathing air. The vortex unit is connected to an external air compressor which can also be used to supply filtered, pressure regulated breathing air which is cooled by a second vortex unit. A safety harness is sewn into the coverall, with the safety harness connected to a pull ring attached to the rear of the coverall. The outer coverall is preferably constructed of KEVLAR cloth to which an external aluminum reflective coating is applied.
