Shelter is of paramount importance to your survival. Staying out of the weather preserves your body's resources for producing heat. Rain, wind, snow can all deplete you of your body heat. Lose too much of it and you go into hypothermia. By including appropriate survival shelter supplies in your survival kit, you will be able to stay out of the weather and increase your chances of survival.
Shelter Items to Keep the Weather Off
Emergency blankets have been around for years. Recent technological advances have made them more durable by making them with polyethylene material instead of the old style Mylar material. Heatsheets™ brand products are all made with this newer more durable material and are definitely a step up from the old style.
A poncho provides its own shelter and keeps the rain off of you. You can also make an improvised shelter by stringing it up as an overhead cover. A tube tent is a premade emergency tent that sets up in minutes. It helps to keep you out of the wind and provides a dry sleeping space. The thermal blanket is a heavy duty emergency blanket that is very durable. It is much thicker than the regular mylar blankets.
