These items can be assembled separately, or purchased as a kit. A bag of kitty litter or sand is also great to have to place under tires for traction in the snow. In addition to items for car repairs, you need to make sure that you have items that would take care of your personal comfort and support in case of an emergency.

The more heat you can keep trapped next to your body, the less heat you'll need to worry about generating. When selecting clothing to store, keep in mind that wool is the best natural insulator. It will help keep you warm even when it's wet. Clothes with synthetic fibers, such as polypropylene, are also good, especially if your skin is sensitive to wool. Cotton, however, is a poor choice because it is a non-insulating fabric and will absorb water.
