A protective body heat retaining pod that is carried in a folded condition within a special purpose backpack attached at the rear of a harness that is worn over a conventional life jacket by both civilian and military personnel who find themselves in or about to enter a cold water environment while awaiting rescue from an emergency situation. A hood to be pulled over the head and cinched tightly around the face of the wearer is attached to the back of the protective body heat retaining pod. The protective pod has a sealed body portion that fits around the legs, arms and torso of the wearer within which a small volume of water is trapped and heated by the wearer's body heat to slow a drop in the wearer's body temperature. A cinching cord is attached to the bottom and sides of the protective pod to be pulled upwardly by the wearer, whereby the protective pod is correspondingly pulled upwardly and inwardly to draw and hold the wearer's legs in a fetal position so as to reduce the size of the body portion and thereby minimize the volume of water to be trapped and heated therewithin.
