Abstract: A disposable multilayer sleeveless heated vest contains an integrated heated element which does not require an electrical power source or secondary heat sources to initially function and can be disposed of after use. The present invention comprises a front and rear section, a plurality of lateral fasteners, and a plurality of heat source compartments. Both the front and rear sections comprises an inner layer and an outer layer. The inner layer is insulated and moisture absorbent while the outer layer is moisture resistant. The plurality of lateral fasteners detachably couple the front and rear sections to a user's torso. The plurality of heat source compartments are positioned on both the front and rear sections and house the air activated heat source elements. The heat source elements provide heat to the user's torso until deactivating or removed by the user, at which point the user discards the vest.
