A bug-out bag is a portable kit that contains the items one would require to survive for seventy two hours when evacuating from a disaster. It is also known as a 72-hour kit, a grab bag,a battle box, and other popular names include GO Bag and GOOD (Get Out Of Dodge)bag. The focus is on evacuation, rather than long-term survival, distinguishing the bug-out bag from a survival kit, a boating or aviation emergency kit, or a fixed-site disaster supplies kit. The kits are also popular in the survivalism subculture. (From Wikipedia -

_________________________________
The bug-out-bag is probably the most clichéd emergency preparation in  the history of survivaldom.  Some people focus so much on compiling  their BOB that they lose track of much more important survival matters,  while others are so biased against the ‘bug out’ concept that they  refuse to even consider putting one together.  In the world of survival  research, preppers sometimes position themselves on the far ends of the  opinion spectrum.  To be sure, some strategies simply do not work and  will never work, and to be uncompromising in those instances is  reasonable, especially when you are dealing with such extremes as  economic collapse.  However, in my endless war against ‘assumption’, I  would point out that rigidity in thinking often leads to tragedy for  those in the midst of a social breakdown.  Adaptability is the key to  survival, and because of this, we cannot discount certain options out of  hand.
The bug-out-bag should not be a primary concern of the survivalist,  but it should be somewhere on their list.  First and foremost, those who  wish to prepare for a collapse event or other disaster should focus on  survival location (where will you be safest? At home, or at a retreat?),  food storage (a year’s worth for each person in your family or group is  really the bare minimum, though some retreatists have the skill to get  by on less), water allocation (if the tap stops running, how will you  maintain a water supply?  Remember, the average person can die after  three days without water), and self defense (how are you going to defend  the supplies you have from those wandering looters who did not prepare?   How many people do you know that you can actually count on to stand  their ground when the situation grows truly frightening?)  If you  haven’t already addressed these important issues, having a BOB will do  you no good.
Have you ever watched a boxing or martial arts match and known  immediately which guy was going to lose?  That’s how I feel about those  people who are obsessed with the bug-out strategy.  They have lost  before the fight has even begun.
On the other hand, there are those preppers who believe they are so  safe in their survival location that they can’t be bothered with  secondary retreats or even a bug-out-bag.  This is equally foolish.  As  intuitive and as well researched as survivalists are, we still have no  way of knowing what would really happen in the event of a total  meltdown.  Could your homestead be the future site of a refugee highway?   Could your retreat and your independence be considered a threat by  “authorities” intent on restoring their brand of order?  Could a poorly  maintained campfire on one side of your county set a forest fire that  sweeps through to the other side, right through your home where you have  staked all your survival hopes?  There are an infinite number of  reasons why you may one day have to leave your primary retreat location,  possibly without warning.  No one is invincible, and sometimes it’s  better to walk away and live to fight another day.  This is where the  BOB comes in…
The bug-out-bag offers you a CHANCE at survival when all else seems  lost.  This is its purpose.  The more ingenuity invested in the design  of your BOB, the better your chance will be.  Finding items and tools  that streamline efficiency, space, weight, or serve two or more  functions at once is crucial in organizing a high performance pack.  In  this way, building a BOB becomes a sort of art form.  In this article,  we will go over some great methods for taking your bug-out-bag to the  next level.
Bug Out Bag Essentials
Most people who frequent survival sites are well aware of BOB basics.  For the sake of those who are new to the concept, I’ll rehash most of  these items (we all started somewhere). It’s possible I will forget to  include some gear that people find essential. Hey, there’s a lot to  remember! By all means, please leave a comment listing the items you  believe should be included, but don’t send me emails admonishing me for  my negligence (I once left out ‘toilet paper’ in a survival gear article  and received dozens of finger-wagging letters in my mailbox).
The items below should adequately cover the Big Four; food, water,  shelter, and self defense, as well as the special tools used in their  acquisition, and those items required for personal health.
Bug-Out Backpack: A lot of people forget to include research  on the ‘bag’ part of the “bug-out-bag”. Your choice of pack is probably  the most important of all, and will affect your comfort and efficiency  throughout any survival situation. Things to consider include size,  durability, as well as how much you can honestly carry over long  distances.
Most hiking packs are categorized by size, which measures their  carrying capacity in liters. Smaller packs, or ‘daypacks’ are usually  between 15 and 35 liters, multi-day packs range between 40 to 75 liters.  For your purposes, a multi-day pack is the best choice.
Some packs are set on a frame which helps your body in supporting the  weight of your gear over long distances. I have found though that a  frame is not absolutely necessary and tends to be a matter of  preference. Military ‘molle’ wear also offers the ability to easily  strap compatible pouches onto your existing bag
There seems to be quite an ongoing debate among survivalists as to  the “appearance” of the BOB pack. On one side, people hold that military  grade bags in camo should be standard. On the other, people scoff at  the idea of hiking across the countryside in military gear, possibly  scaring the bejeezus out of everyone you come across. My personal take;  go for the military style gear, or at least look for very subdued and  earthy colors. I find that the anti-military gear argument is rather  faulty. In a collapse scenario that is so disastrous it calls for a  survivalist to “bug out”, it seems rather unlikely that the average  person you run into will be in a position to care about what you are  wearing, let alone be able to do anything about it. If a prepper was to  run around in combat duds and a camo combat pack today, I would call him  crazy. In a social breakdown tomorrow, I would call him smart.
Camo makes you less visible. I’m not sure what the problem is here.  Unless you enjoy being chased relentlessly by thugs and maniacs, I  suggest choosing a military surplus pack over that nifty new bright red  JanSport.
Bug-Out Food: Food acquisition is probably the most  difficult obstacle in a bug-out scenario. Weight and space are at a  premium. You could load up enough food in your pack to last you a week  or more, but that would leave little space for anything else. This is  where you have to apply the art of efficiency.
What you are looking for are food items that cover a wide range of  health requirements, contain a high amount of calories, and take up very  little space. I have found that protein and energy bars, trail mixes,  chocolates, and jerky, are all perfect for the BOB. Peanuts and other  legumes are very high in calories (some trail mixes contain over 1000  calories in a single cup). Protein bars usually hold around 250 to 300  calories in a very small package, not to mention, they are a good source  of necessary vitamins and minerals. Jerky is not very high in calories,  but it does give you protein and that satisfying feeling of “fullness”,  which is sometimes just as important. Chocolate is high in calories,  fats, and sugars. In our regular environment where active people are  rare, we are taught to avoid these things, but in a survival situation,  you want as much calories, sugar, and fat as you can get!
Despite these space saving foods, your supplies will run out quickly,  likely far faster than you had hoped. Prepare for this eventuality  carefully. Memorize the wild edible plants common to your region of the  country, and carry a small edible plant guide for good measure (never  forget, dandelions are your friend). Be sure to carry snare wire for  catching small game, and a small fishing kit with extra hooks, sinkers,  and strong line.
Survival fishing is not a leisure activity. You will not need a rod  and you will not be sitting around waiting for a bite. Staking a line  across a river with several baited hooks for the day is your best chance  of catching at least one if not several fish, all while your out making  better use of your time. Gill Nets are also an option, though illegal  for sport fishing in most states today, it is doubtful you will care  much during a collapse.
Hunting will be difficult. Carrying more than one standard firearm  when bugging out is not recommended, and if you have to choose only one,  take your primary defense weapon. There are options, though. A combat  rifle in .308 can also be loaded with hunting ammo for large game,  serving two purposes at once. Another option, for smaller game, is the  Henry AR-7 .22 rifle, which weighs less than a full canteen, collapses  down into its waterproof floating stock, and is acceptably accurate out  to 50 yards:
While perhaps a little too bulky to fit inside your pack, it could  still be easily strapped to the side of your pack and the extra weight  is negligible. 200 rounds of .22 LR ammo weighs virtually nothing and  can be nestled into your BOB without trouble.
Bug-Out Water: Water is a weight killer. Don’t expect to  carry much. Plan your bug-out route to intersect natural water sources,  and carry at least one thick plastic sheet, garbage bag, or poncho for  rain collection in conjunction with your canteen. Water purifying  tablets are great in the short term, but a portable water filtration  unit is a must for longer term situations, especially when dealing with  very dirty water sources. The Katadyn Hiker Pro is one of the most  common units used today and the filters are widely available in sporting  goods stores:
There are many other brands available, but I would stress using  filters that are common, mainly because you are more likely to find  replacement filters for trade in a post-collapse environment. Be sure to  stock at least one extra filter cartridge to avoid having to make this  trade too soon.
Bug-Out Shelter: Hopefully, if you have to bug out, you  already have a pre-planned destination. There is nothing more dangerous  than wandering around aimlessly during a collapse hoping to stumble  across a good situation. As you travel, you will need temporary shelters  to get you to that designated primary shelter.
Hiking anywhere takes a lot of energy, and you will probably need to  set camp at some point along the way. In a group, you can sleep in  shifts while others stand watch. If you are alone, the safety hazards  are considerable. Sleeping at all will take effort due to the pressing  uncertainty in the back of your mind, especially when a single moment of  unconsciousness could leave you vulnerable.
Carrying a tent, even a top of the line lightweight all-season tent,  is not realistic during a bug-out trek. The extra weight could be used  for more important items, such as food, and one can easily build a  makeshift shelter from available materials. 550 paracord is extremely  useful in shelter construction. Plastic zip ties also work well. Dead  wood from the forest floor supplies the rest. Choosing the right  location is the number one priority. On high ground, in treacherous  terrain, away from water sources, is actually ideal. The harder it is  for you to get to your temporary shelter, the harder it will be for  other people to get there as well. Terrain alone can deter most would be  attackers. Generally, looters and other undesirables look for easy prey  on easy ground.

Using existing rock formations, fallen trees, caves, etc. helps to  obscure your presence, and covering your shelter with live mosses and  fauna blends its shape in with the surroundings. A heavy duty thermal  blanket can be used to insulate your shelter during cold nights. Light  and fire discipline cannot be overstated, which is another reason why  eating foods that require no preparation is important, at least a  majority of the time. The goal is to avoid altercation, to go as  unnoticed as possible until you reach your primary retreat.
Bug-Out Health: Without your health, you aren’t worth much  to anyone, especially yourself. A bug-out event favors those who are  energetic, athletic, and immune system conscious. Before an event even  occurs, you should already be focusing on improving the mechanics of  your body to the utmost precision. You should be a fine tuned and  flexible machine (or at least as close as you can get). This includes  the old guys out there who are grumbling at me as they read this. I’m  not old, but I’m not so young anymore either. If you are serious about  survival preparation, exercise a little everyday, and I mean EVERYDAY,  especially jogging for endurance.
Get off the garbage prepackaged foods filled with poisonous chemicals  and preservatives. Go organic if you can afford it. Quit smoking, quit  drinking (at least cut down. No one can resist a good beer every once in  a while, not even me), quit heavy drug use (this includes illegal and  legal psychotropic substances), and get in shape for heaven’s sake! I  know, it sounds like I’m telling you to have no fun. I’m not. I’m  telling you to have a little less fun for the sake of your own survival.  It’s worth it, trust me.
Pack wool socks. If you damage your feet due to cold, and lose your  mobility, you will not survive. Frostbite is a notorious problem in  survival situations.
Include a ‘snivel kit’ in your pack for minor illness and injury,  with bandages, aspirin, pepto chewables, etc. I hate to say it, but  diarrhea will probably be a more formidable enemy than any looters you  might come across in a bug-out scenario. Normally, it’s just a minor  irritation, but during a collapse, it could easily dehydrate and kill  you. Packing preventative medications and choosing your water sources  carefully could save you from a most excruciating experience.
Use herbal supplements or teas, like Echinacea and Elderberry, to  maintain a resilient immune system. I have not used any antibiotics or  vaccinations in a decade and I am rarely ill. Your immune system can  handle almost anything if you take care of it properly.
Pack a camper towel and biodegradable liquid camper soap. Stay clean  as often as possible. Take good care of your teeth! Imagine a tooth  problem during a bug-out! Carry non-fluoride baking soda toothpaste and a  brush. Use a dab of peroxide to kill germs. Not only does this save you  from tooth loss, it also keeps your smile pretty, which seems  irrelevant, but during a collapse, you need every advantage. Flash a  rotted gnarly grin at someone who could help you, and they will  instinctively want to walk the other way, no matter how nice you act.  That’s just how people are. Keeping teeth white during a collapse? Try  eating wild strawberries or strawberries from a garden if you can.  Strawberries are filled with malic acid, which removes plaque.
Rest when you are sick, even if it takes a few days. Do not try to  push on until you have battled your cold or flu back. Otherwise, it will  stick with you for weeks, and even cause serious damage.

This seems like an incredible amount of items to carry around on your  back, but all of it should fit quite easily into your BOB if you use  the space wisely, and the weight should not be an issue. Pack contents  will also vary depending on personal survival strategies, but most of  these tools should be present in your bag regardless of conditions.
Advanced Bug-Out Gear
So now that you have all your essentials organized, and have found that  you actually still have room in your pack for more goodies, you’re  wondering what items could give you that extra edge, that advantage that  tips the odds in your favor. Let’s go over a few special pieces of gear  that could make bugging out much easier.
Brunton 26 Folding Solar Panels
: The Brunton 26 is just the  right size for your bug-out-bag; not too big, but not so small that it  has trouble charging your electronic items. I have this system myself  and have no complaints. A small intermediary battery pack may be  necessary though when connecting to such items as 15 minute battery  chargers, so that current is properly regulated. I can think of numerous  electronics that are useful during a collapse, and these durable solar  panels ensure they will always be operational.
Two Way Radios: If you travel by yourself, these aren’t very  practical to carry, but if you are working in a group, they are a must.  There are many models to choose from, but finding a set with security  and private channel options is a priority, ensuring that other people  will not be listening in on your conversations. They often advertise a  range of 15 miles or more, but their real range when not in perfectly  flat terrain usually ends up being around 2-3 miles, which should still  be adequate for your purposes.
Night Vision, IR Flashlight: I’ve written quite a bit about  night vision for the survivalist, and I think the advantages are  obvious. I suggest buying a decent but cheaper model, and then finding a  powerful IR Flashlight. Night vision uses IR rays like an invisible  spotlight, and adding another IR flashlight could increase your range  greatly.
Mini-Digital Video Camera: This serves several purposes. It  can be used for surveillance and for mapping dangerous areas. Instead of  sitting in a hazardous place drawing a site picture, you can walk up,  take a minute of video, and then walk away for later viewing. Another  use; video diary. If you are alone in a survival situation, you might  find yourself losing your mental composure. Talking to the camera and  recording your thoughts might take the edge off the tension and help you  get through alive. Finally, you never know what you might see on your  trek. Perhaps things no one would believe if you told them. Video  evidence might be important, even during a collapse.
Shotgun Signal Alarm: A cheap trip wire device that sets off  a blank 12 gauge shell, or sometimes a flare. Gives you a heads up and a  head start on anyone moving towards your camp. Also can deter those who  now know that you know that they are coming.
Smoke Grenade: These are perfectly legal to own and not too  difficult to find on the web for purchase. Especially useful during an  ambush in which you are at a severe disadvantage. Gives you an  opportunity to make a clean getaway, or at least buys you time to find a  better tactical position.
NukAlert Key Chain: You never know what you might run into  during a collapse, especially if international tensions are involved. A  meter which is always running and alerts you when approaching dangerous  radioactivity could save your life. Though most highly volatile gamma  radiation falls to safe levels after two weeks of initial exposure, you  should still be concerned about consumption of affected substances.  Irradiated water sources, for instance, are undetectable to the eye, and  without a device like the NukAlert, you would never know what you were  drinking. The device is very small, and is also designed to be immune  against an Electromagnetic Pulse.
The Most Important Bug-Out Tool Of All 
I could probably go on for another several pages about gear options  and items, but that would be overlooking the most important tools of  all; your brain, and your spirit.
Smart survivalists, with a solid knowledge base and a powerful  intuition, are the most likely to succeed under the worst of conditions.  Intelligent, logical, and precise action can turn a catastrophe into  any other day, and this is no exaggeration. Most catastrophes befall  those who are unprepared, those who lack knowledge. For the smart  survivalist, a catastrophe is simply an obstacle he has already trained  to remove, and nothing to be overly frightened of.
The spirited survivalist draws on an inexhaustible well of  determination. He is like a human avalanche, bursting through any  barrier no matter how impassable it might seem. He never stops. He never  gives up. He knows there is ALWAYS a way, an answer to any problem. He  understands that most people who die in survival situations die on the  inside first. They give in to the elements psychologically, and the rest  follows from there.
A bug-out event is definitely one of the worst scenarios I can think  of, mainly because it involves so many unknowns. But, with a well  planned BOB, a level head, and a defiant heart, nothing is impossible.  You can live through it. Never forget it. It can be done!

Sidenote: This is just one variation of a BOB. It'll vary based on your situation/needs/location. I'm currently putting together a couple of emergency backpacks (1 to leave in truck, 1 for home). Will post it here when fully assembled. If you have one at home, even a very basic one - feel free to send me photos and a list of what you have, Would be more than happy to post it here.
