I think it's interesting that this thread basically took a turn to the zombie apocolypse lol

I carry one first aid kit no matter what I'm doing. It's probably a bit larger than some because I assume that people I hike with don't have their own and I know I would offer mine and leave myself with nothing left.

I keep the obvious things like band aids, antiseptic creams, gauze, but I also keep things that I know personally work like Rawleigh Salve, Sting Stop for bees/insect bites, and pain relievers. I don't keep anything to pack knife or gunshot wounds or anything like that. That would be more for the end of the world packs, which I don't own.
