Ok, here are my thoughts and suggestions. I have more time in the woods doing this sort of thing than most, for what it's worth.
SHELTER
3 Contractor bags
Windbreaker (recommendations?) Go with a natural color that is also waterproof. All the big brands make a lightweight waterproof breathable shell
2p. Under armor or long johns (recommendations?) What is your climate? If you live in the south, you probably don't need this at all. Otherwise, make sure it is a quality product that will wick moisture and dry quickly (because if you are really bugging out, you may have to exert yourself without stopping to remove the undergarments.
4 Socks You don't need 4 socks. Take an extra pair and whatever is on your feet. You can wear one pair while you dry the other.
4 Hand warmers (maybe?) Ditch the handwarmers. You are most likely going to have to make a small fire when you stop in order to get warm/cook/dry wet clothing/boost morale, so let the fire do the warming. When you are moving you won't need them.
Gloves (recommendation?) Unless the temperature is dropping below about 15 degrees F, you shouldn't need heavy gloves, a basic, comfortable work-glove should do the trick while maintining dexterity. Wear a glove that is too heavy and your hands will just sweat.
Get a big polythelene sheet. It is cheap, small, and compact. Also, some cordage.
TOOLS
Compass
Maps
3 Microlights Lights are a luxury, and in an emergency (the kind you are preparing for by packing ammunition) are often a liability. You will only need to use them intermittently and for very short periods of time. A single microlight will do just fine.
Radio (what kind?) Get a cheap multiband radio. You can get ones that will receive international broadcasts as well as NOAA updates and are the size of an old FM walkman
3 Folding razors Razors are good, but make sure you include at least one sturdy knife and small sharpening stone. You will use the knife for everything from splitting wood to skinning game.
Romisen RC-G2 1xAA LED Ditch the LED, or the Microlights, you won't need both
Folding shovel Go with a folding Trowel. As a single person, you won't be digging any fighting positions, and even catholes are more for courtesy than necessity. You will need to dig to make a Dakota Firehole (google it), as it is probably the most efficient, and stealthy way to make a fire, and the trowel will be more than adequate, though if you have a good knive, that will work too
Wire saw or other compact saw (what kind?)Don't get a wire saw. They are neat, but break very quickly, trust me. If a wire saw is all you have, make sure you build an old-style frame for it that will help prevent the blade from flexing. Otherwise you will likely only get to make a couple of cuts before the blade breaks due to fatigue. You can purchase survival saws that are basically chainsaw blades with handles (I think someone posted one earlier in this thread. They hold up
2 Sporks 1 of everything redundant. A safety net is nice, but a spork isn't exactly a life or death item. Do you plan on carrying all this stuff?
Hammer/Nails (What kind?) Absolutely not! You won't be buildign for a while. if you are on the run you won't be able to afford the extra weight or the time to build. If society has deteriorated to the point where you are building long-term structures, that sort of thing should be easy to come by.
Can opener Make it a multitool and you can knock off the screwdriver too.
Screwdriver
EOD breacher bar wrapped with paracord You need Paracord, but a good knife should do the job of the breacher bar and others as well. If you find yourself having to breach structures, alone, by force, just throw a rock through a window and climb in.
Needle/threat Throw in a few fishooks as they take up almost no space
Bic Lighter!
FOOD
Olive oil
Protein source - powders, tuna, beef jerky
MREs
Psyllium fiber
Sodium
Coffee
Seasoning
I would pack a couple energy bars to sustain an initial run, a single MRE stripped down to the bare essentials for an emergency, and some dry foodstuffs for preparation as time allows. Freeze dried items are best as you can simply add water and eat if cooking isn't practical. Some sodium is important, but your body can get by with very little salt intake. Ditch the olive oil, it will make you sick if you just try to eat it, and MRE's are already plenty rich enough.
FIRE
3 Lighters (what kind?) One butane lighter, it will last a long time and you have redundancy in the items below
3 boxes Waterproof matches One Box
Tinder (25% steel wool, 25% vaseline, 50% dryer lint) Just buy a couple hexamine tablets, they are very cheap, and work not only as tinder, but as a fuel source to heat water, etc. They will do a much better job, and you can throw a couple hexamine tablets, some matches, and a striker in a film cannister
Magnesium starter Good tool, but you might as well not bother if you are going to have a lighter and matches
Metal pot Too big and bulky. If you have to carry something, go with a metal cup, maybe a Sierra Cup, as it will be big enough to cook in, but small and light
Lighter fluid Dont' bother, it is more likely leak and ruin your food/water/clothing than to be necessary, especially with hexamine.
H2O
Water purification tabs
Container (what kind?) I just keep 2 liters of bottled water, it doubles as a container and as water. But I live in NC where water is easy to come by. If you are in the deser, obviously, you will need more. Water bottles are abandoned all over the place, it shouldn't be hard to collect addional containers if it becomes necessary.
H2O (how much? worth taking?)
DEFENSE
50 rounds 9mm NATO FMJ Might as well go with hollowpoints. I would also only take loaded magazines.
20 rounds #3 buck, 20 ga.
10 hollow point 20 ga slugs (copper?)
SIGNAL
5 Flares If you are running away (hence the BOB) then flares are not going to help you as you will either be running from the law, or society has temporarily collapsed
Signal mirror Usefull only as a shaving device if you are really bugging out
Air horn (what kind?) You have guns right? They are louder than any airhorn
Whistle (what kind?) If you have room for a whistle, go for it, but see above.
FOOD GATHERING/HUNTING
20 rounds 9mm Subsonic (what kind?) 9mm subsonic is still loud fired out of a pistol. You might as well carry a few extra regular 9 mil rounds and some snare wire.
20 rounds #7.5 20 gauge
5 Pre-made snares (what kind?) Make sure you have extra snare wire, it goes quick
Slingshot (maybe? what kind?) dont' bother, your snares will do the work for you if you place them right. Unless you are a slignshot guru, I guarantee you will waste days missing that squirrel.
2 Fishing setup(s) (what kind?)
CHEAP 20 gauge youth model with barrel off for portability, screw on as needed (anyone know a brand that is decent and goes for <$60 used?)
1ST AID ETC
Snake kit (what kind?) A razor and a suction device are probably all that you will be able to get use out of
20 Benadryl
Rubbing alcohol (or what?) no alcohol, go with betadine or somethign more effective.
Nail clip
Potassium iodide
Cotton buy some curlex, it is cheap and surves several purposes
Epi-pen
Bandages Purchase an Ace Wrap, and a military bandage
25 Ibuprofen
Antibiotic ointment
Antibiotic meds (what kind?) Cipro, as it cures most stomach ailments (which is what you are most likely to need antibiotics for.
What else??
A small wilderness survival manual/ book on Ditch Medicine
MISC
ID
Cheese-cloth
Fuel replacement (for car...need a brand-name for this, wal-mart used to carry it, gets you about 15-20 miles extra on empty)
20 Caffeine tabs
Sunglasses
Sunblock (what kind?) Ditch the sunblock and wear a boonie hat (also helps camoflage)
Bug spray/wipes (what kind?)
Hat
5 Cigars
Shemagh Great in the desert, but aren't typically worn outside the middle east/africa because their usefullness is limited to that sort of climate.
"Axe" body spray It will only attract bugs, take up space, and make you easier to 'sniff out'
Deodorant won't help you survive
Sharpening stone
Rope (what kind, how much) 550 cord is almost perfect for what you need, don't bother with heavy rope as how often do you really NEED to rappel off that cliff?
Para cord (how much?)
5 Batteries for radio and light
Waterproof paper
2 Pens How about 1 Sharpie and a couple pieces of paper? Do you plan on writing a dissertation or keeping a journal? Do you really need to do those things?
Sharpie
Toothbrush Another luxury, break off a young twig and use the broken end, works fine.
Floss Floss is actually really handy, though less for flossing than for other things.
5 Candles (what kind?) Light is a luxury, though a candle can help get a fire lit. Ditch 4 of them if not all.
Small Bible
Small Constitution
Compact manuals: navigation, medical, wild foods, field dressing
Cards
2 bars Soap Another luxury, people survived for thousands of years before soap was discovered
Monocular (what kind?)
2 Ear plugs Go for it as long as you don't try to put them in before you get in a fight. You won't have enough ammunition to do any noticable damage.
$50

Are you planning on carrying this? Have you put it together yet and how much does it weigh?
