You didn't specify pocket in your initial post so I haven't been operating under that assumption. And I have more than one pocket so have never felt limited to one pocket.

You should get a tiny AM-FM radio. Or a headset radio. I would not want to be walking around the metro area in a disaster without news reports. This Sony armband AM-FM-Weather radio looks good:

On 9/11, pedestrians and drivers here were starved for news as the attacks were unfolding. They needed news reports to base their decisions on whether to evacuate and where to go as roads were being closed and bridges were affected -- especially in Arlington in proximity to the Pentagon.

My neighbors and I were out on the sidewalk during much of the 9/11 exodus, letting drivers know what we were hearing and seeing on television.

I've carried a radio in my purse ever since. Next to the Petzl Zipka headlamp.
