What ever you carry your kit in I would strongly suggest that it be on your person rather than in your bag or pack. A kit that is in your pack, back in camp, will do you no good when you tumble down a hill on the way to the stream for water. I carry my kit in a belt bag. That way it is always on me.
I have just engrained into myself NEVER to step away from the truck or camp without my survival kit (and my first-aid kit is part of that). I am allergic to bees and there is a strong possibility that just getting into the pack, let alone going to get it, might be all the time I have. But,
that is very excellent advice. contents:
antibiotic ointment, various band-aids, small micro cloth, meds, magnifier, mirror, matches (I have those every packed in everything -paranoid like Pathfinder), and when I hunt I add... a few "lady" things
. That's kinda the minimum I carry.
