Thermic C-Pack 1300 Batteries

Therm-ic C-Pack 1300 batteries power Therm-ic heated insoles, giving up to 13 hours of heat on one charge across three heat settings. They are a straightforward, non-Bluetooth battery pack.

The trade-off is that they work only within Therm-ic's insole system: the Heat Flat, Heat 3D and Heat Kit ranges. They are not a universal battery for other heated gear.

They are for skiers who already run Therm-ic heated insoles and want replacement or extra batteries, and for anyone building a heated setup from a Heat Kit. Therm-ic's heating element can be trimmed to your insole and can stick to Sidas custom footbeds or Sidas insoles, so it pairs well with a custom boot fit.

Check that your insoles are from the Heat Flat, Heat 3D or Heat Kit range before buying, and ask us if you are not sure which you have.

We think warm feet are the difference between a good day and a great one, and these keep the heat going all day.
