The fact is that the same type of survival food must be stored in a backpack or survival bag for emergencies. It would be highly impractical to carry cans of food on your back as the weight would certainly exceed the usual 65 pounds allotted for backpack use. Also, canned foods will require some method of disposing of the trash cans when you finish your meal.
You can still bring another easy, light meal. Take a trip to your local sporting goods store and pick up some of the dehydrated foods that come packaged in small bags for campers and hikers. Many websites offer lightweight survival bags and also provide free worldwide delivery with every purchase.
Although there are many brands available, the mountain house brand may be one of the tastiest options. With these meals, you just have to add boiling water to the food bag and wait a few minutes for the liquid to be absorbed and you are ready to enjoy a tasty and quick meal. These foods are available in single-person bags for up to 4 or more people. You will find a wide variety of foods to choose from that are sure to please all tastes.
When creating an ultimate survival bag, it is important to pack as light as possible in case you might end up traveling on foot. Since every extra ounce of weight will eventually end up strapped to your back, you need to plan your accessories accordingly.
