Now that you know what a EDC is lets look at its grown up version, a B.O.B.(Bug Out Bag). This is your GTFOOD(get The Fuck Out Of Dodge)/WTSHTF(when the shit hits the fan) bag for you to simply grab and go. The sole purpose of it is for you to store in it all that you can(safely) carry with you when and if you ever have to bug out. Now idealy you will be able to carry what you and yours need to bug out to a more secure location. One of the biggest mistakes you can make is trying to simply bug out and live out of your pack. There is no way in hell that the average joe will be able to survive long term on what can be put in a B.O.B.. If you are highly experienced with wilderness living, know how to rough it, find, capture and prepare wild game and plants you will fare much better, so unless you posses said skills have at least 2 locations scouted and stocked for your arival and long or short term stay. 

That being said, be awere that in a SHTF situation you can trust no one, yes it sounds like some paranoid corny X-Files stuff but there is much wisdom in the idea. Just think, what would you do to keep you and your family safe and taken care of anything and everything right? thought so, and guess what you aint the only one. that is just what everyone will be doing. If they have no family with them, they will look out for #1 first  that being themselves. Your best freind may have some food when you are starving and he/she wont share, would you be prepared to fight them for it, how bout kill them over it? Scoff if you will but it just may come down to that, as i said, Trust no one, family, friends, strangers, government, military etc. Another bit of wisdom is Allways Be Prepared, anyone who was a scout growing should remeber that little gem. Again may sound dumb but its one of those pieces of wisdom you need to take to heart, that applies to a B.O.B, to car maintenance to anything else you can think of. 

Now, the following is a basic outline of the basics you need to carry in your B.O.B. and on your person in a Bug_Out situation. For a good pack avoid civillian packs, start with a military pack, best one is the ALICE(All-purpose Lightweight Individual Carrying Equipment) Pack, they are lightweight and very durable. For a B.O.B. they are a very good start. Keep in mind also that in a B.O.S(Bug Out Situation) that if you wander around looking like Rambo, Mad Max or like the Military folks will either avoid you like the plauge or swarm you in fear/anger. Military surplus gear is great and often times beats any civilian gear but dont relie on it. Also aquire as manu survival PDF's, Books, Articles and manuels as you can and become very well versed with the content and try to keep copies in your B.O.B. but not if they take up too much space. One last tip, Use and test any and all objects you plan to use in a B.O.B., you dont want to be in the middle of the wilderness and find out you are too dumb to use a magnesium fire starter or that you are alergic to the food in your MRE's.

Good Luck.

Water purifiacation tablets-at least 3 bottles. used to purify drinking water and kill bacteria.

PotassiumIodine antiradiation pills-used to block absorbtion of radiation by the thyroid gland take as many as you can get your hands on

First Aid Kit-Here you must carefully balance between space and use. the main things are guaze, anispetic, scissors, ointments for rashes and other, medical gloves, penicillan, syrenges, asprin as well as snake bite kits, bee sting kits if your allergic. Just use common sense and read up on first aid.

Sewing Kit-Usefull for mending clothing, stiching up wounds, sewing up holes in tents, tarps, sleeping bags etc.

Knives-Get at least 5 good folding lock blade style knives. Why so many you ask well, blades break in the dark one may fall out of your pocket on the ground and you dont notice for hours not to mention the multitude of daily uses, cutting strips of cloth for a tourniqueit, self defense, carving wood for skewers etc.......  Also get a good buck knife or fighting knife for self defense.

Point is its better to have many and not need it than to need one and not have it.

FlashLight-again same as with knives and guns better to be safe than sorry. get severel good LED lights, MAGLITE is a good place to go. get a few in varying sizes, smaller ones can be mounted using a clip.Also try Surefire.

Headlamp-mainly used by cave exploerers, they fit on your head via adjustable straps. get one with a red, blue and normal light filters, preferably with LED lights.

Batteries-Dont go get the cheapies that wear out in a day but there is no need to spring  $30 for a 4 pack of AA's either. Try and get recgargable batteries and have enough for what ever needs them.

Hand Crank Radio/Generator-Let me explain, this is a mid sized radio that runs off a hand crank generator. Most models have a feture to recharge batteries manuely, plug in a cell phone and provide light.

Duct Tape-At minimum take 2 full rolls. used for a restraint, cover up a hole in fabric, tape a splint, tape together objects to conserve space etc. Duct tape as 1,001 uses  and odds are you can thing of a few more, just get a few rolls, i dont care what color just get it.

Lighters-A good zippo windproof lighter and a few cheap Bic lighters are a good start as they are pretty easy to get and take up very little space. A better one is the Firestorm-Storm proof lighter as its water proof when sealed and is good for 80,000 uses. though id get a few of both for good measure and dont forget the extra fuel.

Water Proof Matches-You can buy these or make them by dipping match heads into melted wax. very light wieght even with a few thousand they take up almost no space, may also a a usefull bartering item.

Magnesium Firestarter-a solid magnesium block that has a stricking flint on it. all you have to do is shave off a few strips of the magnesium block and strike the meatl bar on top with a knife blade along it to create a shower of sparks that can instantly ignite a 5400 deg fire.Very basic, a must for any survival kit.

Tinder-Dryer lent, cotton balls dipped in vasoline, a oil soaked rag cut into strips, basicly things that will catch fire and hold it ot get a fire going. This way you can make a firestarter last longer by not using the magnesium everytime, you only need for the tinder to catch a spark and then use the fire to start a campfire for warmth or cooking.

Boots-Unless you live in a small town or can Bug out quickly odds are you will be on foot alot. Now sneakers may be more cofortable but they wont hold up on rugged terrain. work boots are ok but they are a bit too heavy for moving quickly  (trust me on this, you ever tried running long distance in heavy work boots? Well i have and it will wear you out fast). I have two pairs of boot i wear on a daily basis the newer pair are Magnum stealth 2 boots. very light, breathable, ankle support and just comfterble. the other pair is Biltrite Combat boots i got surpluss. they havent been made since the 1970's.

While the magnum boots  are good for every day wear, they are made of nylon and soft leather and they lack a steel toe cap. The combat boots are a little less comfy the are made of tough hardend water proofed leather and they have a steel toe. I got the magnums for about $70 and the Biltrite for free though they havent been made since the 70's. Both are excellent but it all depends on the terain you will be on. check this site for ideas,

Gloves-you need gloves. for lugging a pack around, comeing in contact with people, working etc. Keep at least 3 pairs of gloves, the first would be a pair of  work gloves,  just some good leather work gloves. 2d would be a pair of tactical nomex/kevlar blended gloves. Provides cut protection and flame protection, i wouldnt so much as touch a person with out them on. Third, a light pair of grip gloves. the ones with girp beads on the fingers and palms, these would be the ones i wear by defualt. As with all the gear on here wear them, try them get used to them.

Cell Phone-everyone has one nowadays and it would be a good idea to use it in the early days of a bug out, though after about a week i would dismantle it or cease to use it. Dont waste your cash on some expensive one though, just get a basic one.

2 way radios-get a set for your self as well as freinds and family. good one have a range of up to 26 miles and multiple channels. many models have regargable batteries as well.

Parachute Cord-get at least a 50 yard strand per person. can be used to rapelling, a hammock, snare, ETC. 

Handguns-A pistol or revolver in a .22LR, 9MM, .45 and .38 special. the .22LR is probly pound for pound the best ammo you can get your hands on. it works in rifles, pistols and revolvers and has all most no kick making it great for anyone to be able to use. its also about 2 cents per round, compare to 24 cents per round of 9mm. .45 ACP is for pure stopping power, it will drop a man dead at medium ranges should you need it for that purpose and has great stopping power even on a vest. the .38 special would be my back up just in case i need to get off a shot and dont have time to reload. if you have the cash id get a .357 or even a .500 but i would hold my breath on that.

Ammo-There are 3 main types of ammo you want to stock up on.

.22LR
.9mm

12 guage shells.

those are the 3 most common ammo types in the world. I would get 10,000 rounds of .22lr, and 2,000 each of 12 guage and 9mm. it will be heavy but well worh it. odds are that when it gets to the situation in which youll need this all, our current currency will have no value whatsoever. you can use these rounds as a bartering tool for tradeing.

Sleeping bag/Tent-For a tent get a small tent made for 2 at the most. ive found a few that fit 2 and weigh just 3 pounds. you can tie the tent to the pack. as for a sleeping bag, depending on were you live and are planning to bug out to id get a 3-4 season rated sleeping bag. also id get one rated for at lead -35'f below zero.

Folding Trench Shovel-an invaulable tool. most fold to small enough to fit in a cargo pant pocket. use for digging a fire pit, a shelter, ETC. each member of your party needs one of these.

Ax-No not the body spary, a solid wood or synthetic handled ax or hatchet. In addition to being a good weapon, you will likely need it to fall trees for shelter and wire wood no B.O.B. should be with out one.

Emergency Blanket-more commonly called stadium blankets, you know the giant silver blankets you see at foot ball games in the winter. They fold to the size of your palm and bottle in warmth, plus ive found them for about 3.25-3.75 apeice.

Wool Blanket-or just a good heavy blanket, can be used as a mat, shaw, cover, makeshift tent, door way closure etc.

M.R.E.'S, Meals Ready To Eat. Dehydrated air tight pre-packedged meals used often by the military. all they require is water then heat them up or eat cold. they have shelf lifes of nearly ten years in some cases and weigh only a few ounces. Also, check out Hooah Bars

Drinking water-This is probably the most important item on the list. You can last a couple of weeks with little or no food but only about 5-6 days without water. If you go buy my guide lines above for a pack with a 3 liter bladder you will want to refill the baldder every day to every other day depending on the ammount of physical activity you par take in day to day. And dont forget to boil the water and purify it to kill as many parasites as possible.
