I think there could be many answers here. In general, this is a question from the category of “what would you take to a desert island.” But let’s look at the situation from the other side: “bag-out bag” means a set, which contains the basic things necessary for survival in an emergency. So, don’t you carry such a bag with you every day? Essentially, your everyday accessory is your survival kit.
You keep documents, money, pain pills, credit cards, a photo of a loved one, and maybe even a pair of lock picks to crack your home door. That’s what you think can be useful based on your life experience.
So, I think this set is individual. I have listed the universal things above. The rest – you choose especially for yourself. Perhaps these are allergy pills or a can of air for asthmatics. Or maybe it’s a couple of packs of condoms (which is also necessary for survival).
But if you still meant a bag for a desert island, then I would definitely put a radio phone and a representative of Oriflame there, because this person will always find a way to other people.
