Start with warmth and clothing. Blankets are non-negotiable; consider wool or Mylar space blankets for superior insulation Intermountain Healthcare. These lightweight blankets reflect body heat and can be a lifesaver. Pack extra gloves, hats, and warm layers, especially if you have passengers or if your own gear might get wet Red Cross. Consider including hand warmers for an extra boost of warmth. If you anticipate being stranded for a while, a change of dry socks can also make a significant difference in comfort and preventing hypothermia.
