I think there are enough newer members to start this again but amazingly, AOM had the almost exact same conversation about 4 or 5 years ago.
For me its wallet, phone, and keys if I can get away with only that.
I think we had this conversation a month or two ago as well, haha.
House keys minimum. Normally my phone but not always. If I need it cash or card. Rarely more than that.
Normal things for me to carry: thin wallet, keys, cap stick, and cell phone. Luckily being the technology person I am, everything I need is accessed on the smart phone :P Except for maybe a knife, but then again we just need to invent the iKnife and we're set. There can be an app for that I swear.
Cell phone, keys, wallet is the bare minimum for me, although I tend to carry a lot of stuff sometimes. Among the bigger things I've carried in my pocket are a book (about the size of those cheesy paperbacks you buy at airports, not a textbook, obviously) or my tablet (one of those 7" ones, not an iPad, obviously.)
You sir have big pockets. I cannot ever get a 7" tablet in my pockets :P
Maybe Old Navy just makes their pockets big. I can fit one into the pocket of one of my ON jeans; have never tried with any other pants. And it's not as if I wear plus-size clothing either; I'm actually a really skinny guy. I was surprised too.
I don't carry these *every* day but if could, I'd feel my essentials would be:
-small corn cob pipe and favorite tobacco
-paracord wrist bracelet
