Every winter, many people consider that even their most insulated jackets are not enough to keep them warm. Some avoid the heavier insulated jackets because they are too bulky or weigh too much. How about having “jacket warmers”? If someone has invented feet warmers, why not apply the same idea to warmers that can be placed inside of a jacket? These warmers would be activated when bend, and would last for several hours. They would be flat and light in order to make them convenient to carry more in a bag or purse.
