This is a great thread! My BOL is a bit far, so I want to be able to live out of my pack if I have to. Here's what I have:
1.) Water: I carry a platypus 2 liter water sack and a second bottle for carrying water, a lifestraw, and polar pure tablets, and aquamira drops, all in different locations. water is important so redundancy with this is a must
2.) Shelter: this is my heaviest and most expensive gear, I have a Celty 15 degree sleeping bag, a large tarp, an inflatable pad, and some paracord
3.) Fire: magnesium fire starter, a bic lighter, and a small baggy of vaseline-soaked dryer lint
4.) First Aid/Hygiene Kit: This contains gauze bandages, moleskin, ointments, quickclot, soap strips, wet wipes, benadryl, pain reliever, toilet paper, tampons, chapstick, toothbrush/paste
5.) Socks and other clothes: 3 extra pairs of socks: 1 merino wool, 1 synthetic wicking sports socks, and a pair of toe socks to relieve friction. Also underwear and a rain poncho
6.) Navigation: Terrain and road map of my area, compass for navigating
7.) Gerber knife
8.) Cooking: Wood gasifier stove and titanium pot - for cooking food, will even burn damp bits of wood
9.) Sewing/repair kit: with basic repair stuff for all my gear as well as some wire and fishing line for snares, duct tape, also good for sewing up wounds
10.) Food: I have nuts and dried fruit, cliff bars, some dehydrated meals, PB, and ramen noodles. Also a few salt and hot sauce packets.
I also have other things like cash, a headlamp, extra batteries, a copy of my passport, and my edc gun and ammo that would come with me as well. And a mini seed bank of some heirloom basics just in case I can't ever get back, since it's tiny and weighs almost nothing, it's worth the weight.
My baseweight is about 15lbs, total weight about 20-25 depending on how much water and food I have, which is pretty good, I think.
