When I'm out and about, I have my wallet (I recently found a really nice slim wallet, called the Allett), my key ring (car key, Gerber multi-tool, micro-usb flash drive, RSA secure ID), cigar tube (to keep/ extinguish/ relight a cigar), lighter, and phone. If I wear cargo shorts, I've got every pocket filled-up. In jacket weather (more than half the year up here) it's not an issue. But in the summer, I really should have a bag or backpack, but I don't want to drag one around. Women get to have a handbag, it's easy for them.
