I have three. One for my car, one for my wife's car, and one for our F250 4x4 pickup. Although we have no "combat" clothes, our clothes come mainly from older hunting, camping clothes, especially old wool sweaters, socks, shirts, pants, and jackets, that are still servicable, but not used hunting anymore. In an emergency, they'll do just fine. Who cares about a moth hole or two, or a small tear.
In addition, we have the standard "emergency" equipment, food, water, wool blankets, First Aid, tools, etc., etc., etc.
For many years, living in So. Kalif., we carried these -- as we called them -- "earthquake kits" -- in our vehicles, in the event a devastating earthquake struck while we were away from home, perhaps making it necessary to abandon the vehicle, shoulder the "kit," and walk home.
Now, living in Idaho, the kits have been modified a bit, mainly in the clothing area, and are our "Winter Emergency Kits." One thing we always carried, and still do, is a complete set of maps, for anywhere we live and travel. Nice to know where you are, and how to get home, if necessary.
I am an Eagle Scout. Although I attained that rank many, many years ago, I still adhere to the BSA Motto, "Be Prepared."
