Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
The compass will get you moving in the right direction but when night descends you’ll need a strong dependable light source and the J5 Tactical flashlight is that and more. The J5 produces an incredibly intense beam from a single AA battery. It’s essential survival gear that can be seen from miles away so even if you can’t see anyone else there’s a good chance someone else will see you.
I'm not quite crazy enough to say that epinephrine will help you survive the inevitable zombie apocalypse (you can go here for that). I'm just suggesting in a roundabout way that if you happened to be in a situation where something was trying to eat you, the increased heart rate and blood flow to your muscles brought on by a well-timed dose might just save your life.
Preparing for catastrophic or short range survival is extremely personal and most of us keep it tight to our chest. I think PowderKeg says it best – Invisible and then Nuttus who knows that not all of us are the same skill or wherewithal stage, yet as a TEAM we shore up each others weaknesses, learn off each others strengths and it is a continual building process going forward.
If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals. The pommel at the butt end can be used to hammer tent stakes and that little thing hanging from the lanyard cord is a powerful emergency whistle that can take over emergency signaling duties from the tactical flashlight or your long range walkie talkies when the sun comes up. A top-notch knife like this is essential survival gear.
GPS is great but what happens when your battery dies, and you don’t have a portable battery handy? The compass is the one piece of survival gear that will never let you down. Sure, it can’t tell you if there’s a town nearby but it can prevent you from wandering aimlessly in circles. The Eyesky compass is designed specifically to help extricate you from emergency situations. It features conversion charts to measure distances, a rotating bezel ring to determine your heading and adjustable sight lines to plot your course. It’s also built to last. It will take you all of an afternoon to learn how to use the Eyesky compass and it may turn out to be the most valuable afternoon you ever spent.
The term "survival kit" may also refer to the larger, portable survival kits prepared by survivalists, called "bug-out bags" (BOBs), "Personal Emergency Relocation Kits" (PERKs) or "get out of Dodge" (GOOD) kits, which are packed into backpacks, or even duffel bags. These kits are designed specifically to be more easily carried by the individual in case alternate forms of transportation are unavailable or impossible to use.
In addition, the kits may contain typical individual "survival kit" items, such as nylon tarps, extra clothes and coats, blankets, sleeping bags, matches or other fire starting equipment, a compass and maps, flashlights, toilet paper, soap, a pocket knife and bowie knife, a fishing kit, a portable camping stove, a power inverter, backpack, paper and pencil, a signaling mirror, whistle, cable saw, bleach, insect repellent, magnifying glass, rope and nylon cord, pulleys, and a pistol and ammunition.
Other small kits are wearable and built into everyday carry survival bracelets or belts. Most often these are paracord bracelets with tools woven inside. Several tools such as firestarter, buckles, whistles and compass are on the exterior of the gear and smaller tools are woven inside the jewelry or belt and only accessible by taking the bracelet apart.
No, it’s not going to last very long on the South Col of Everest but if you’ve become lost or separated with your hunting knife or camping expedition this incredibly light and convenient emergency tent is crucial survival gear that can provide enough shelter to get you through the night and then some. It can be fully deployed in just minutes and is capable of retaining up to 90% of your body heat while providing an effective windbreak and precipitation shield. At 8’ x 5’ it can also easily accommodate 2 adults. Cheap, effective, practical survival kit for all types of outdoor adventurers.
The most dangerous people in a survival situation is the gang of outlaws who only want to take what they need and don’t care about what happens to the owner(s). The hardest to know what to do with, and for, is the individual (person or family) who has done nothing to prepare for emergencies or disaster. It’s hard to want to help someone who does not, and will not, help themselves. But it’s endemic to our society – it’s all about big brother taking care of you, or “the government” being your friend. It’s about entitlement. It’s about not caring about other people, only yourself/family. They are the 2 true dangers to preppers.
Based on this crude but honest assessment of the general public's affinity for the common bicarbonate, you'd be surprised by how much survivalists are into it (#2 on the list of "things for preppers to hoard"). They must expect some pretty serious hankerings for tasty leavened baked goods, or they have extensive phobias about the funkiness of their nuke survival backup plans.
Survival kits, in a variety of sizes, contain supplies and tools to provide a survivor with basic shelter against the elements, help him or her to keep warm, meet basic health and first aid needs, provide food and water, signal to rescuers, and assist in finding the way back to help. Supplies in a survival kit normally contain a knife (often a Swiss army knife or a multi-tool), matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.
Food supplies in a bug-out vehicle include hundreds of pounds of wheat, rice, and beans, and enough honey, powdered milk, canned goods, bottled fruit, vitamins, dehydrated fruits and vegetables, salt, pepper, spices, and oil for several months. In addition, the kits often contain high-calorie energy bars, a cooking kit, utensils, liquid soap, and towels. The water supplies may include bottled water, filtering kit, bottles, collapsible water containers, and chlorine bleach for water purification. Food preparation and washing equipment may include items such as a grain grinder, a bread mixer, a strainer, a manual can opener, a steam canner with canning jars and O-rings, cutlery, knives, an electric 12-volt cooler icebox, kerosene lamps and heaters, kerosene or propane stoves, extra fuel, a clothes wringer, a foot-operated treadle sewing machine, and an electric hot plate (which would require an inverter to operate off a car battery).
The only shortage is diminutive size of the primary blade. Other than that it rates inclusion in any serious gear collection just by virtue of the plethora of options it presents you with and the quality of its construction. The handles on the OHT (One Hand Tool) display a graphic of the tool folded in beneath them so you don’t have to waste time guessing in survival situations. And the entire device is designed specifically to be operated with one hand, which in some survival situations is all you have to spare. A great piece of survival gear you shouldn’t be without.
