I developed a few lists for a couple different “BoB’s”.
Focus on the "Essentials":
Essentials:
Appropriate and seasonal clothing
Shelter (I include cordage – about 50-100 feet of 550 cord)
Water
Fire
Water (procuring, purifying/filtering, transporting)
Food
Tool (read as “Blade or multitool”

Navigation (i.e. compass/map)
Signaling (flashlight, whistle, signal mirror, cell phone, Shortwave/WX radio for receiving)
First Aid (kit, sunscreen, prescription meds)
Self Defense (hiking stick, firearm, etc….my addition)
Understand that everybody’s situation is going to be a little different:
Staying home?
Getting home?
Leaving home for another destination?
Rural or Urban location?
Terrain – open, wooded, swamp, waterways, etc.
Season
Distance
Transportation type (Public, car/truck, motorcycle, bike, etc.)
Any medical concerns?
Current physical fitness?
Are you trained in martial arts or have a Carry Concealed Permit...can you carry at work?
Have you reconnoitered your routes?
Water sources along your route?
Do you have alternate routes?
Have you identified hazard areas or choke points along your bug out/bug home route?
Sorry…a lot to consider on top of just cramming stuff in a backpack. Whatever you finally decide on, spend a couple nights camping with your BoB. Figure out what works, what doesn’t, how it carries, what’s missing, what can be dropped. If you plan on doing anything by foot, make sure you have a comfortable pack and you’ve done at least some walking/hiking with it. Don’ t forget to pack some separate clothes if your daily attire isn’t conducive to hiking (quality boots/shoes).
Also consider what you EDC (Every Day Carry). A lot of handy tools and "essentials" can be carried even in ordinary clothing attire...LED flashlight, folding or even fixed blade, a little 550-cord, compass, CCW, whistle, etc.
Hope that helps a little,
