The Therm-ic Smartpack 1200 is no longer available. It was discontinued in 2017.
Please view our current selection of Therm-ic boot heaters.
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 with the Classic insoles are possibly the easiest to install and suitable for any boot and shoes. 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.
