Abstract
Portable multi-layer warmth delivery systems and methods may pertain to an electrically resistive first layer, a structural second layer, and an infrared-redirecting third layer. By passing an electrical current through the electrically resistive first layer, infrared energy is emitted, redirected, and efficiently concentrated in a vicinity.
