I'm with Greg on this one.
I don't think a pocket kit is the answer.

You need at least a small backpack for your urban survival needs. Some items like a spare pair of sneakers, a warm fleece jacket, a quart of water, a flashlight (w. batteries), and some energy bars are bulky. But they are necessary. Some warm gloves and a beret (or a fleece hat) are also good ideas.

I suggest that you expand the volume of your gear a little bit.
