Self-Warming

The Self-Warming Jacket that Charges via USB

"This looks like a pretty normal Columbia jacket, right? You might even have one that looks just like it. Still, I bet your jacket doesn’t have a built-in battery pack that powers its handy-dandy self-heating feature. Rechargable via USB, the jacket was designed by a former Intel engineer and has a heat-conductive carbon fiber mesh running through it. That battery pack we mentioned earlier is good for five hours."
