Therm-ic boot heater systems are designed to combat sub-zero temperatures and ensures that your winter sport experience is enjoyable. The Therm-ic boot heating system is easy to use, easy to install and suitable for any boot. The Therm-ic SmartPack 1200 PowerPack with the Classic Heated Insoles is easy to install. The SmartPack 1200 Powerpacks are unique because they use Lithium-ion batteries which are lighter in weight than AA or nickel metal hydride batteries. Lithium-ion batteries weigh almost half of what the other system batteries weigh and are smaller in size.
