The BOBs I'm making are for 2 adults and up to two (Grand) children. The parameters I've set up for these bug-out-bags include being both a manageable size and weight for one person, with enough food and water for 72 hours, and other survival necessities to last a lifetime.
Each BOB includes two military poncho liners that may also be used for blankets. These are polyester batting and liner and they are tough to compress by hand. Also in the BOB is a 1.5 gallon collapsible water container and 4 bottles of treatment (I chose treatment over filtration so it can be done on the move). I decided to compress all these components via vacuum encapsulation and was pleased with the results.
The space saved is at least half and if the packages are opened, the blanket can still be rolled and stowed in the expanded vacuum bag; the water container and treatment bottles can be stowed in an included 4 mil poly zip lock.
The 186 piece first aid kits include added antibacterial wipes and good particulate masks. I will encapsulate these kits as well for long term storage and so the BOBs are absolutely complete when needed.
Our families have always been avid campers so the use of most of these materials will not be foreign to them. During our next family reunion, we'll meet and go over some of the details with which some will not be familiar, including, use of the radios, GPS, cell phone charger options (solar and/or crank), use of the compass, signal mirrors, etc. We'll also discuss situational awareness and decision making for various events in the locations where they live.
We're all having a good time with this project and this forum has helped considerably.
