Shelter or warmth

A variety of materials are recommended for emergency shelter, and vary between geographic regions. Options often included in survival kits may consist of:

• Reflective "aluminized" (Mylar coated) space blanket or survival blanket to retain body heat (and signal)
• Lightweight poncho for protection against wind and rain
• "Tube tent" or bivvy bag
• Tarp with grommets or tie-tapes (best if nylon or polyester)
• Large plastic trash bag as poncho or expedient shelter roof
• Ferrocerium rod (AKA "Metal match", "Hot Spark", "Firesteel", "Magnesium fire starter") and fire striker for fire-starting, Fire piston or Solar Spark Lighter
• Waterproof matches or lighter
• Cotton balls or pads smeared with petroleum jelly for fire starting (can be carried in 35 mm film container, zip lock baggie or heat-sealed inside large diameter plastic straw)
• Catalytic heater and bottled gas fuel
• Canteen full of water, and a filter if needed
