In pockets or on person:
cell phone, small pocketknife, lighter, firesteel, flashlight
In jacket (about 3 feet away most of the day):
small Doug Ritter based survival kit, with water purification tabs and Immodeium added, oh and some toilet paper too, all kept in a soft-side first aid zippered pouch.
In car or carried around in a daypack ( I have 5 of these packs made up), my "man" purse as my friends call it (I think they're just jealous

)
fixed blade, tarp, blanket, hat, gloves, extra socks, full-blown firestarting kit with firesteel, lighter, PJ cottonballs, some tinder, Esbit stove and tablets, matches, powerbars, nalgene bottle, steel cup, paracord, first aid supplies, Leatherman Wave, bandana, poncho, compass, and more than I can remember off the top of my head at this time. All the essentials I may need to survive.
I had a friend ask me why I carried all that "crap" around. I responded that if the SHTF, that "crap" as he called it and the knowledge I have to use it may make the difference between life or death. He laughed and asked if I was crazy. I shrugged. Why argue?
