KLIM’s new eFire heated technology features one horizontal panel on the upper chest and two vertical panels on the upper back designed specifically for women. The heating element includes three heat modes – low, medium and high – with long-lasting heating filaments powered by a USB-C charged battery and a dedicated battery pouch in a hidden zipper battery pocket.
