Life Giving Warmth is a small, California based copany with the US patent for a blanket powered by a battery. We manufacture and distribute battery-powered heating blankets for soccer/hockey/football moms, campers, RVers, the military, first responders, etc. We believe our highly water resistant Kodiak Battery Powered Heating Blanket would be a great fit for all hunters for those cold days in the deer stand or the duck blind. It provides 3+ hours of continuous heat per charge. (less)
