A flexible heater is disclosed herein having a base substrate or sheet carrying a plurality of spaced apart electrically resistive strips overlapping layers or grids of conductive strips arranged in spaced apart relationship next to each other to form a plurality of intersections with the resistive strips which, when connected, define and form an electrical resistive component of a given value. Each grid is composed of an electrical conductive material such as silver, aluminum or the like while the resistive component may be composed of carbon. The heater is employed as a hand-held unit, an insert or a portion of an article of clothing such as a boot, shoe, glove, jacket or the like. A power source is detachably provided for energizing the electrical components.
