The term "bug-out bag" is related to, and possibly derived from, the "bail-out bag" emergency kit many military aviators carry. In the United States, the term refers to the Korean War practice of the U.S. Army designating alternative defensive positions, in the event that the units had to retreat. They were directed to "bug out" when being overrun was imminent. The term has since been adopted by military training institutions around the world, with Standard Operating Procedures involving a bug out location, a method of withdrawal, and the bare supplies needed to withdraw quickly but still survive in the field. The concept passed into wide usage among other military and law enforcement personnel, though the "bail-out bag" is as likely to include emergency gear for going into an emergency situation as for escaping an emergency.
When creating your plan, make sure that it can be used for the many different worst-case scenarios that can happen. Take a look at the different types of disasters that are likely to happen in your area and make sure you have a deep multi-scenario plan for each.Some people fall into the trap where they think that they are prepared, but it's been so long since they have checked in on that plan that they really don't remember it, or circumstances have changed that make it important to change your plan. For instance, you may have some food stored up, but have you checked the expiration dates lately?
I like your addition of a bug net. One thing I noticed is that the author correctly says to save space and weight to just pack a tarp. However, where I live, from late May to late September if you don’t pack bug netting, a tent with screens or plenty of bug spray you are going to be itchy, sore and tired from no sleep because you are up all night swatting mosquitoes
Sleeping bag. Sleeping bags present an interesting size and weight problem and for that they’ve landed on our “probably want” list. You can make do without one by wrapping yourself in multiple thermal blankets, or Amazon sells an awesome Tummah Emergency Survival Mylar Thermal Sleeping Bag that weighs less than 4 ounces. It’s not as comfortable as a big fluffy sleeping bag but it’s light and will keep you warm at night.
