Stay warm and comfortable outdoors no matter the weather with the COLDPROOF Lightweight Portable Heating Pad. Easily getting power from a power bank, this compact heating pad serves up even and constant heat anywhere you take it. In fact, it uses heating technology originally developed by NASA. It disperses 113°F of even heat in a unidirectional format. This means the heat only comes out the side you need, rather than heating up the object it’s sitting on. Thanks to its super-thin dimensions, you can tuck it under your seat on snowmobile, lawnmower, or even in the stands as you support your football team mid-January. And, because you can use your own power bank, you can effectively choose how long you want COLDPROOF to run. Whether you need it for a quick mid-winter walk with the dog or for a weekend-long camping trip, COLDPROOF is there to keep you cozy.
