Mylar emergency blankets are great survival gear but sometimes you need more than that. The Coleman North Rim Extreme Weather Bag will keep you cozy warm when the air temperature is 0 degrees Fahrenheit. In temperatures like that you can lapse into hypothermia quickly especially if you’ve been slogging through the woods all day and are sweaty. Just crawl in the North Rim bag and pull the drawstring to lock in the warmth. The cover is durable rip-stop nylon so you can lay it on the ground if need be and there are snag free dual zippers so you can get in and out quickly and easily. Must have survival gear for winter 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.
For a time in the 1970s, the terms survivalist and retreater were used interchangeably. While the term retreater eventually fell into disuse, many who subscribed to it saw retreating as the more rational approach to conflict-avoidance and remote "invisibility". Survivalism, on the other hand, tended to take on a more media-sensationalized, combative, "shoot-it-out-with-the-looters" image.
Say you're at work and a terrorist attack occurs. Roads are closed to any and all traffic but you only want to get home - even if that means walking.
