"I ended up buying a large ALICE pack. I use it for backpack camping but it's also being stocked with other supplies to be used as a multi-day BOB.
I bought the large because I'd rather have a lot of un-used space as opposed to not having enough space when I'm backpack camping.
Right now it has my camping hammock in it. I'm fixing to throw in some fire starting materials, more water and water containment/purification, a first aid and trauma kit, some TP, some light non-perishable meals, 150 foot of para cord (I like to use a lot when I set up camps), some duct tape/zip ties, a large tarp, a decent sleeping bag, some trash bags (preferably the contractor type), some spare clothes and socks, some rain gear, and I'll probably carry a small cook kit. I'll probably use the space in between the back of the pack and the rear of the frame to mount a camping axe as well. I'm probably forgetting something that I'll have stuffed down in there, but whatever.
It will probably have a break down rifle and some spare tools in it too; depending on whether I'm using it as a BOB or a camping rig.

It's not the most comfortable pack I've seen or worn, but I wanted something extra large that would last a lifetime. I'm probably going to upgrade the shoulder straps and add some closed cell foam in the back support area to make it more comfy.

EDIT. I normally carry a toothbrush and toothpaste lol; foot care products as well. "

"Y'all can keep using that military stuff, but it's not for me. Here's part of the reason why:

"You could use a nonchalant bag in case of unwanted attention, baseball bags and guitar bags can be worn on your back and can store weapons and whatever else you need, I would just think you were some crazy thinking he can save music from becoming history or that he would become popular among survivors."

"The bag I am using for my BOB is an old rugby bag, I thought it would be sufficient for the purpose. It's an ugly maroon colour and goes over one shoulder.

I went on a camping trip this past Easter weekend and I took my BOB to see how it would feel lugging it around a little. I am definitely going to be looking for a new bag because after about 100m of walking my shoulder was starting to get quite sore, the bag is definitely not made for comfort. I am glad I tested it before I actually had to bug out or else I would have been in a world of hurt.

I will probably switch it over to a regular backpack until I can find something a little better for the purpose."
