1. An apparatus for heating a human body comprising a vest;
- at least one heater in said vest for heating a torso;
a controller for controlling operation of said heater; and
biofeedback means connected to said controller for detecting skin temperature of the torso and extremities, whereby the controller actuates said heater to heat the torso based on an extremity skin temperature below a threshold value.

Abstract
A heating vest containing heaters for warming the torso, sensors for detecting skin temperature of the torso, and a feedback device for feeding torso skin temperature to a heater controller. Other sensors detect the skin temperature of the extremities which is also fed to the heater controller. Heating of the torso causes warm blood to flow to the extremities to warm the latter, making it possible to work at relatively cold temperatures without thick coverings on the extremities.
