I’m using an Osprey Atmos 65 backpack in large, which gives me actually 68 Liters of space. I chose this particular bag because I already have an idea about how much space I need from using my Camelbak BFM for so many years. I originally got a 5.11 Rush 72 backpack to replace it, after MANY people suggested it and read some really great reviews on it. After thinking it all through, it wasn’t going to work. In order to carry the amount of items I wanted, I’d have to add cargo space to the bag and it already weighed quite a bit. Plus, it’s a very military-looking bag, which I’d rather avoid if I could. It also seals up at the top and has a built-in cover for the rain.
Every bug out bag should be 100% unique. Sure, there are some basic items that every bug out bag should have (food, lighter, water filter, flashlight, etc.), but you should customize your bag based on where you live, what type of disaster is most likely to occur in your area, and how much weight you can carry over a long distance. Many preppers forget about that last point.
Since I live in the desert so I don’t need a lot of cold-weather gear but it does get pretty nippy at night and can easily get below freezing. As you can see in the Clothing Bag above, I have just some basic Army-issue polypros as a backup. I also carry a lightweight rain jacket because not only will it keep the rain off me, it’s a good wind breaker. Once it gets colder, I’ll throw a fleece or something in there. Just make sure you layer your clothes. Sweating in cold weather makes your clothes wet so even after you cool down to the point where you stop sweating, your clothes continue to sweat for you, and you get hypothermia.
Popular modern methods for purifying/treating water include filtering pumps and chemical treatments, such as iodine. These can be efficient and effective solutions if you have access to these items in a survival situation. An herbal treatment is another method in which water may be purified from viruses and bacteria. Grapefruit seed extract is sold as a water purifier, although there is some debate on whether or not it is one hundred percent effective. The most widely used and proven method for safely purifying water is boiling. Bringing water to a boil and allowing it to continue to boil for 2-3 minutes will kill bacteria and viruses.
