Multifunctional wearable heaters have attracted much attention owing to their efficient application in personal thermal management. Inspired by the polar bear's thermal management, a laminated fabric with enhanced photothermal conversion, mid-infrared reflection, thermal insulation, and electrical heating performance was developed in this work, which was made of CNT/cellulose aerogel layers, cotton fabrics, and copper nanowire (CuNW)-based conductive network (CNN) layers. The CNN layer made up of highly conductive CuNWs not only exhibits better conductivity to realize the Joule heating effect but also possesses a human mid-infrared reflection property. Moreover, the other side of the cotton fabric was laminated with CNT/cellulose aerogel, which enables the fabric to have a good photothermal conversion ability and thermal insulation performance. The temperature of the laminated fabric could reach to 70 °C within 80 s under 1.8 V; it requires more than 500 s to return to room temperature (28.7 °C). When the light intensity was adjusted to 1000 W/m<sup>2</sup>, the temperature of the laminated fabric was about 74.0 °C after lighting for 280 s. Our work provides a new approach to improving the performance and energy-saving of personal thermal management fabrics.
