RELATED: The Best Kids Skis, Snowboards & Snow Gear The Torch coat heater is a set of 3 thin heating pads that easily velcro inside any coat you choose. It’s thin enough to go undetected from the outside and powered by a small lithium ion battery that provides up to 5 hours of heat at 4 temperatures: 95 degrees, 115 degrees, 120 degrees, and 135 degrees. It even has “built-in safety features” that prevent it from bursting into flames like the holiday “hoverboard” that nearly roasted your kid. Torch’s creators are trying to crowdfund their patent, and you should get behind their Indiegogo campaign to make sure you have one of the first units when they ship this year. Sure, you won’t be able to use it until next winter, but it’s not like your car is thawing out any time soon, anyway. Buy Now $99
