Selecting the right kit requires an understanding of the situations you’re most likely to need it for. A helpful exercise can be to create a list of 10 items you’d absolutely need in the event of a natural disaster or extended period without power and access to food and water. Then make a list of another 20 to 3o supplies you’d also like to have handy in this situation. This will give you a great baseline to help you narrow down your options.
The term "survival kit" may also refer to the larger, portable survival kits prepared by survivalists, called "bug-out bags" (BOBs), "Personal Emergency Relocation Kits" (PERKs) or "get out of Dodge" (GOOD) kits, which are packed into backpacks, or even duffel bags. These kits are designed specifically to be more easily carried by the individual in case alternate forms of transportation are unavailable or impossible to use.
