I think this is a very interesting product. An actual jacket with built in heater in the front and back. And a charging station for your phone. The jacket is waterproof and the battery for heating lasts up to 14 hours. The cost is very reasonable as well at the sale price of $179.95. I can see someone working outdoors in extremely cold weather finding this very useful. Even for casual use like snowmobiling or walking/hiking in cold temperatures.
