Unlike Mylar® space blankets that can easily tear, this wrap is made from a combination of Mylar and strong, lightweight, polyethylene fabric laminated together. It provides better body heat reflection and durability than traditional Mylar. High-visibility orange on one side and metalized silver on the other, it is a compact solution for keeping patients warm, the last critical phase of the massive hemorrhage, airway, respiration, circulation, and hypothermia prevention (M.A.R.C.H.) treatment algorithm. Silver side can be reversed to deflect solar gain when cooling the patient is vital. Weighing in at only 3.5 oz, this is an essential piece of gear for all responders.
