Quick Answer
For warmth in vehicle break-downs, the best blanket materials are wool, down, or synthetic insulation, such as Polarguard. These materials retain heat well in cold conditions and can be easily stored in a vehicle emergency kit. They are also relatively lightweight and compact.
Choosing the Right Insulation
When selecting a blanket for your cold weather kit, consider the R-value, which measures an insulation’s ability to resist heat flow. A higher R-value indicates better insulation. Look for materials with an R-value of at least 3 to ensure warmth in cold conditions. Wool blankets, for example, have an R-value of around 3.2, making them an excellent choice.
Considerations for Vehicle Storage
When storing a blanket in your vehicle, keep size and weight in mind. A compact blanket that can be easily stored in a glove compartment or under a seat is ideal. Consider a blanket with a compression sack or a roll-up design to save space. You should also think about the blanket’s durability and water resistance, as it may be exposed to the elements in an emergency situation.
Additional Tips and Materials
In addition to blankets, consider adding a warm hat and gloves to your cold weather kit. These items can help retain body heat in cold conditions. You can also use materials like emergency bivvy sacks or space blankets, which are designed for outdoor use and can be easily stowed in a vehicle. When selecting these items, look for materials that meet or exceed military specifications for cold weather gear.
