A: When organizing materials in a tactical backpack there are certain fundamental rules to follow such as packing the sleeping bag at the bottom and placing most of your heaviest items in the center of the bag, with clothing like thermal tops and hiking pants etc above that. If you’re carrying a tent it should be lashed to the side of the pack. Survival gear – like most of the items reviewed above – is often small and light and should be distributed in the exterior pockets of the backpack where it can be easily accessed in an emergency. Place items related to the same task in separate pockets; i.e. place all your fire starting related items in the same ziplock bag and put them in one pocket then put your navigational aids together in another pocket. Things like emergency blankets and Mylar survival tents can go together in another pocket. While your tomahawk should be tucked away in the backpack, your knife should always be carried on your person. If you need to use your survival gear for any reason it should be returned to the same pocket you took it from so there’s no confusion if you need it again.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
