ABSTRACT OF THE DISCLOSURE A motorcycle helmet (10) defines a cavity (13) in a hard fiber shell (17). A thermo-electric heat pump (12) is mounted in the cavity, and a light metal radiator (15) is bonded to both shell (17) and pump (12). One way conductors (14) energize the heat pump (12) from a motorcycle battery source to pump heat from the hard fiber shell (17) to the radiator (15). A flexible bladder (20) filled with heat transfer liquid is mounted in the hard fiber shell (17) and below the heat pump (12) and in thermal contact with a wearer's head and the heat pump (12), for conducting head heat to the pump (12) to electrically pump to the radiator (15) for radiation to the atmosphere.
