If you’re tired of bundling up for the winter in bulky coats and layers of scarves, ThermalTech may have the jacket for you. The start-up claims to have created a line of lightweight jackets that absorb heat from the sun, artificial light sources, and your own body to keep you warmer for longer. According to the company’s IndieGoGo campaign, the jackets are made with a durable stainless steel mesh fabric and can make wearers up to 18 degrees Fahrenheit warmer in a matter of minutes.

The jackets, according to ThermalTech, use “patented, lightweight energy-absorbing fabric technology” to harness ultraviolet light and transform it into heat. The jackets come in different styles, ranging from a lightweight “Street” jacket for casual use, to an “Extreme” coat for snowboarding and skiing. Unfortunately for anyone hoping to grab one this winter, the coats aren’t on the market yet. ThermalTech is raising money for the project and hopes to have the jackets ready by August. Anyone interested in reserving one in advance can do so via IndieGoGo.
