The characteristics of North Face Optoelectronic Down Jacket are super warm, loose-fitting but extremely wrapping. The first touch is high-end texture, and the overall curvature of the wrapping lines is perfect. There is carbon fiber material sewn inside. Carbon fiber is the only non-metallic material with low resistance. When current passes through the carbon fiber material, heat will be generated. If there is resistance, heat will be generated. This is a universal law of nature. Carbon fiber has very stable physical and chemical properties and uses Haoqun's patented technology.

Special substances are added to the fibers to absorb solar energy and convert it into heat energy, and emit far-infrared rays with longer wavelengths to warm the inside of the clothing. By adding heat-sensitive phase change materials to the fiber, heat can be absorbed, stored and released in the form of latent heat. It can transform into solid and liquid states during temperature changes, thereby achieving the effects of absorbing and generating heat.
Most of the electrically heated down jackets currently on the market use electric heating wire or carbon fiber materials, which have relatively low heating efficiency and high power consumption. The biggest disadvantage of using such a material is that it cannot be bent frequently or exposed to the sun for a long time, otherwise it may cause excessive local heating and even cause a fire. If a fire breaks out in down, the consequences can be disastrous.
