In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sun glasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.
Boil water for 10 minutes! Really! This is a myth. When water comes to a boil, thats it, done, finished. The other 9 minutes and 50 seconds are useless, impractical, and stupid. What, are you trying to cook or kill organisms? I like mine well done so I think I will boil them for 15 minutes. But if I want to just kill them I will boil them, when the water boils, they are dead.

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.
Generally speaking, the more outdoor experience you have, the fewer items you’ll need in your survival kit. Those who are quite skilled at starting campfires may not need to bring matches and emergency tinder; as a simple fire starter will suffice. Similarly, experienced outdoor enthusiasts may elect to bring items like garbage bags, rather than ponchos, as they can be used for a variety of different purposes, which outdoor novices are unlikely to have mastered.
During his 45th Infantry Division, Pense taught field wiring, instructing G.I.s on setting poles and stringing wires to rig together a communications network from scratch. After the war, he was an electronics engineer in the private sector, sometimes on military contracts, learning the frailty of the nation’s power grid firsthand. On one government contract, he witnessed a nuclear warhead knock out power in Hawaii after detonating high above the Pacific.
Then, for two hours, Andrew: just tells stories. The time he went after Jesse James’ buried treasure, the time he was held at gunpoint while prospecting for gold, the time an 8-inch centipede fell on him while caving in Japan—each story adorned with cliffhangers and near misses. Andrew: can talk. If he couldn’t, Darryl, a regular attendee, would’ve napped for longer than he did. 
While many outdoor enthusiasts consider the color of a survival kit to be of minor importance, it actually makes good sense to think about this important characteristic. For example, it will be much easier to find your survival kit in an emergency if it is brightly colored or reflective. By contrast, you may find yourself in a situation in which you’ll want to keep a low profile, such as if you are trying to avoid dangerous people. In these cases, you’ll want a black or earth-toned survival kit to help avoid drawing attention to yourself. There are no right or wrong answers in this regard, but you’d be wise to think through the issue carefully before making your choice.
For global catastrophic risks the costs of food storage become impractical for most of the population [54] and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.[55]

I use a big Swiss Army knife and multi tool and knife. I would add, spoon, fork, small stove, pot, isobutane, light tent, sleeping bag+pad, compass and if in mountains an altimeter and paper maps of where you think you are going to be. Instead of flashlight and candles, a headlamp with spare batteries. Raincoat, hat, gloves, food, Grayl water purifyer instead of tablets……all together about 30 lbs of weight. Fits into a 50 liter backpack. Just sharing my experience. It always depends what the purpose of the emergency bag is.

I’m not going to try to candy coat this one. If you need this product, you’re in the middle of a terrorist attack or an act of war using a chemical warfare agent (CWA). The people around you will be dying. You’re going to die, too, if you breathe in these chemicals. But if you only have skin contact with these lethal substances, and you have a decontaminant at hand – you can neutralize them. Let that sink in for a moment. If you only come into contact with a chemical weapon on your skin, there is a product that will counteract most toxins. Now, this isn’t exactly a new product. In fact the company has been making this product for many years, and a friend of mine has successfully used it in “live agent” military training. The part that’s new is that this product is now available to civilians. RSDL is the only decontaminant cleared by the U.S. Food and Drug Administration to remove or neutralize chemical warfare agents such as tabun, sarin, soman, cyclohexyl sarin, VR, VX, mustard gas and T-2 toxin. It’s a simple little packet of lotion-like neutralizer. Each kit comes with instructions and a training product, so you can get a feel for it through realistic practice. It also comes with a packet of decontaminant for one person, which removes the chemical agent from the skin in a single step.
Many books were published in the wake of the Great Recession from 2008 and later offering survival advice for various potential disasters, ranging from an energy shortage and crash to nuclear or biological terrorism. In addition to the 1970s-era books, blogs and Internet forums are popular ways of disseminating survivalism information. Online survival websites and blogs discuss survival vehicles, survival retreats, emerging threats, and list survivalist groups.
