Klim eFire Aggressor Shirt

*The Aggressor eFire shirt adds powered heat elements to the most versatile and comfortable layering system available. Designed specifically for KLIM mid-layers and outerwear, the Aggressor eFire heated base layer traps body heat to ensure consistent warmth for a cold day on the snow.

The heating element includes three heat modes – low, medium and high – with long-lasting heating filaments powered by a USB-C charged battery with a hidden zipper battery pocket.*
