Slid into the back of my backpack is a sheet-sized Fresnel Lens. It weighs so little that it didn’t come up on my scale and since there’s a flat spot that it fits into nicely, it effectively takes up no weight. It’s a no-brainer to get one of these. Here’s a quick video I did showing how easy it is to start a fire with one of these if you have a sunny day and some dry stuff laying around:
I don’t know how much you guys weigh, but ideally the total load you’re carrying should clock in under 1/3rd your body weight. Add to that the fact that you might have to carry the kids for a bit, and you may want to shoot for 1/4 body weight. Since you do have kids I imagine you have a some type of stroller or wagon or some such. Might not be a bad idea to put extra water and consumables in there and tow it instead of carry it. It’ll save you calories, help to keep you from having to carry the kids when little legs get tired, and allow you you to pack a little extra. Shoot for something like a baby jogger though, so it’s at least equal to the same terrain as your kids are.
An excellent resource regarding bug out bags is a new book by Max Cooper called, “Realistic Bug Out Bag, 2nd Edition: Prepared to Survive.” This is a monster book at over 600+ pages. It has scenarios, drills, and is full of useful and insightful information. I like that the author stresses planning and has a section devoted to bug out plans and how to practice & train your plan. The section on self-defense is great. The chapter on trauma has very valuable information. He is also a huge advocate of designing a BOB that fits your needs based on factors that pertain to your situation. I highly recommend this book.
Viral pathogens most often found in water are typically Hepatitis A, Norwalk and Rotovirus, all of which are smaller than most filters are incapable of trapping. They’re species specific which means human to human transmission, and all 3 are associated most often with fecal contamination, thus the further you get from population centers, the lower the risk becomes. For viral coverage, water purification is needed to kill the virus. Chlorine base chemicals are the best treatment next to boiling. UV pens and filter add-ons work good, but are not as effective as heat/chemical treatment. If you know the area you’re heading to, has a previous reputation of human traffic (like campgrounds), then avoid the UV treatment. If the area you’re in is not a high traffic area, UV is alright for use, but personally, I’d rather heat or chemically treat to be sure, and just bypass the expense and extra weight of a UV purifier.
The bag can be loaded and then cinched down with compression straps to keep your gear from shifting. The bag has 11 different exterior pouches allowing for good organization. The bag comes loaded with PALS webbing which allows any MOLLE webbing accessory to be added. The price point is good since the quality is high and the pack is so large.  The carrying capacity of the bag is 173 liters and comes with a Lifetime Warranty.
The Garmin High Sensitivity GPS tool is a potentially game changing piece of survival gear that employs a quad-helix antenna and GLONASS receiver to provide actionable GPS data even when you’re in the gnarliest locales. With its comprehensive selection of pre-loaded US topographical reference maps you’ll be able to plot an effective escape route from even the direst situations.
You now have a foolproof method of navigation and enough light. But you need to sleep and eat. The Gerber Bear Grylls Ultimate pro knife with its full tang 4 ¾” high carbon steel blade is just the piece of survival gear you need to help you harvest materials for an emergency shelter, get a fire started, open cans and if necessary, dress wounds and cut bandages.

One thing that the article doesn’t reference is “How many people will there be in your Bug Out party?” The point being, that although there are some items that need to be in everyones B.O.B, there are others that don’t require duplication. Figuring out which items can be used by all the members of your party can reduce duplicating these items in each bag. For example, does everyone in your party need to carry a 1 quart backpacking pot, or will 1 or 2 suffice for your whole group? Those types of items can then be parceled out to the members of the group, and cut the weight down.
Keep in mind this is my personal bug out bag list. I say it’s the ultimate bag because it’s better than anything I can come up with for my circumstances, that takes into consideration my budget, my skills (and lack thereof in some cases), my geographic area, my 25-pound dry weight limit I imposed, and what my most likely scenarios for using it are. There is no perfect or ultimate bug out bag that will work for everyone. Also, some of this stuff I chose because I already had it and some of it I paid more than most people are willing to spend.
Design – The best bug out bag is one with plenty of pockets. This allows you to compartmentalize your bug out bag essentials so that you know exactly where everything is and you don’t have to dig through mountains of other stuff to find what you need. Put all your fire and light things together such as tactical flashlight, candles, headlamp, fire starting kit and storm proof matches. Put maps, GPS devices, compass and other navigation related items in their own pocket and so on. The more you can separate things the easier it will be to transcend your difficulties.
All of our hunter–gatherer ancestors had classification systems for living organisms, knew their names, understood their uses, recognized how they inter-related to each other, and were aware of exactly how to utilize those resources in a sustainable fashion. This knowledge was at the foundation of their ability to thrive within the natural environment.
Often survival practitioners will carry with them a "survival kit". This consists of various items that seem necessary or useful for potential survival situations, depending on anticipated challenges and location. Supplies in a survival kit vary greatly by anticipated needs. For wilderness survival, they often contain items like a knife, water container, fire starting apparatus, first aid equipment, food obtaining devices (snare wire, fish hooks, firearms, or other,) a light, navigational aids, and signalling or communications devices. Often these items will have multiple possible uses as space and weight are often at a premium.
I appreciate the philosophy, and the focus on quality, thoughtfulness, and multiple usage tools more than anything. If that was my gear (and I know it ain’t) the only thing I’d change is a small pair of channel locks instead of the wrench. They’re handier for taking pots off the fire than needle nose, still do about 90% of the things a little c-wrench will, and give a good grip on things when you need it.
Don’t forget spices and nutritional supplements. Yes, you can plan a well-balanced diet with prepared foods, but not everyone has the same taste. Spices and herbs allow you to change up the flavor of the same basic ingredients for variety and interest. Vitamins and supplements are an important addition to your emergency supply stash. Choose nutrition bars, protein powder, or multivitamin capsules that support nutrition and boost natural immunity.
Paracord is one of the most versatile pieces of survival gear you can carry. It has applications as diverse as helping you set up a makeshift tent to creating a clothesline for drying wet clothes to establishing a perimeter around your campsite that will warn you of the approach of curious or hungry mammals. On top of that you can use it to transcend physical obstacles like small cliffs you might encounter as you attempt to reach civilization. It’s essential survival gear for the person that likes to be prepared for any eventuality.

I’ve spent a lot of time thinking this one through. Don’t give me that crap about having electronics being a stupid idea because I hear THAT stupid idea from someone every time the topic is brought up. The fact is that 99.9999999% of anything you’d ever use your bug out bag for will allow you to use your electronics so not reaping the benefit of what this stuff can do for you is just plain stupid. If somehow an EMP/CME does wipe out EVERYTHING I have, then I just drop the bag – simple solution. In the meantime, I carry this stuff.
To the extent that stress results from testing human limits, the benefits of learning to function under stress and determining those limits may outweigh the downside of stress.[15] There are certain strategies and mental tools that can help people cope better in a survival situation, including focusing on manageable tasks, having a Plan B available and recognizing denial.[16]
Ideally, when traveling in the wilderness, it is best to carry multiple fire-starting tools, such as a lighter, matches, flint and steel, etc… Even with these implements starting a fire can be challenging in inclement weather. We highly recommend practicing fire starting in different weather conditions within different habitats. Good fire-making skills are invaluable. If you were to find yourself in a situation without a modern fire-making implement, fire by friction is the most effective primitive technique. Popular friction fire-making methods include bow drill, hand drill, fire plow, and fire saw.
