Pocket raincoat

I have found a brilliant product in (of all places) my fave book store: the EMERGENCY RAIN PONCHO. I like to walk about town carrying nothing outside my pockets, and it has often been ruined by the simple prospect of rain, prompting me to bring at least a bag-umbrella, and thus a bag. But this little package weighs nothing and fits in a small pocket, so my carefree and footloose walk style is undisturbed. I love it.
