There are unlimited sources for bug-out bag lists, but you should also consider your own unique circumstances and specific needs (don’t just purchase a generic kit and call it good). Everybody's kit will be different, but each should have the basics. You should be able to carry your own kit, as well as someone else’s, if they (kids, older people, pets) can’t. Mine weighs more than the recommended 25 percent of your body weight, but I've made sure I can lift, stand and hike with it if required.
The pack that I use has an extremely practical and cool feature, a smaller backpack that zips onto the larger pack. I've loaded what I consider to be the most critical items in the smaller pack, so I'm still ready if I only have room/energy for the smaller pack.
These items are not in order of importance. Wherever possible, and practical, I use resealable and/or space saver bags-both to protect stuff and to have the bags available.
Small (Critical Items) Pack:
Water filtration system, steel cup and collapsible water bottle
Fire starter and candles
Headlamp with spare batteries
Comprehensive first-aid kit (also includes trauma equipment, rubbing alcohol, saline, dental floss for sutures, etc.)
Duct tape, paracord, zip ties
Whistle (I like the Storm brand)
Fleece stocking cap
Clothes (including waterproof stuff)
Neoprene work gloves
Nitrile gloves (also in first-aid kit)
Alcohol wipes (also in first-aid kit)
Orange safety vest
Orange surveyor's tape
Strobing (clip on) blinker
Breathing mask (dust, etc.)
Copies of important documents and information
Cash (small and larger bills)
Personal defense tools go on my person
In the larger pack (which zips to the smaller)
Solar charging panel and adaptors
Quick-dry microfiber towel
Large garbage bags (the dark, thick ones)
Waterproof pads-can be used together as tarp or individually to carry, wrap, funnel, etc.
Toothbrush and toothpaste
Additional first-aid supplies (to supplement those in small pack)
Playing cards (aside from obvious use, can also be used for paper, etc.)
Peabody's pack-is sized specifically to go into her carrier, just in case we need that for transport, shelter, etc. The carrier has a shoulder strap, so I can have both hands free, even with all the kits on me. (It won’t be pretty, but….)
Food and treats
Stainless-steel food and water bowls
First-aid kit (I put together dog specific gear)
Extra copies of rabies and other vaccinations, vet contact info, etc.
Extra collars, including lighted collar
Extra ID tags (carrier, harnesses and collars also have ID attached)
Blinker light (can attach to leash, collar, harness, etc.)
