That’s like me saying you are wrong to recommend a .22 because it would eventually succumb to the end of the world and become useless as pellets dry up, don’t bother wasting your time packing a finite resource, a knife will do everything for you, it will rebuild society!! But as you unwittingly acknowledged, you pack the .22 knowing it will be useful at first and will eventually become nothing more than an ornament you could discard or stash somewhere safely in case you ever come across more ammunition.

Size – Everyone overestimates how much they’re carrying when they go backpacking (if everyone who claimed to carry a 100 pound pack actually did we’d have thousands of hiker deaths every year in the US alone). But a survival situation is one time when you need to be cold-light-of-day honest about how much you can carry and what that load should be comprised of to give you the best possible chance of survival. As a general rule you shouldn’t carry more than 15 or 20% of your body weight, which for most people will be between 20 and 40 pounds. With this in mind you’ll want to take into consideration the weight of the pack itself (which must be deducted from the total load) and its volume so that you wind up with a bug out backpack that can carry the appropriate amount of supplies.
Great read & outstanding list of items. Extremely helpful & very much appreciated. While I’ve found over the decades that there are usually several ways to accomplish most things, focusing on the core items/goal while adapting to the situations & environment an individual(s) find themselves in is crucial. You can have everything known to man & still have limited skills/experience leaving you vulnerable. You can have all the skills but arrogance & overconfidence can do you in. Applicable intelligence, balance in actions/approach to problem solving on the fly & practice with skills/preps can make the difference in most cases. So one has a 35 year supply of beans and rice, great to have no doubt, but who wouldn’t trade some of it for a coke and some M&Ms for normalcy occasionally? That may be just enough encouragement to get the companions/family through to safety. Again, it’s all a wag for the most part…do what preps you can, develop usable skills…plan, persevere & prevail. Fantastic prep checklist & ideas…thanks! Proverbs 27-17…As iron sharpens iron, so on man sharpens another!
