This may seem silly, but we bring the white kitchen trash bags. Combine that with a baseball cap and you get a pretty good set of rain gear. Make a hole in the top front of the bag (not the seam) and then rip arm holes once the "hat" part is on the head. Put the baseball cap on top to hold the hood in place. The wet hat helps keep you cool after the rain and the whole bag can go right in the trash after the rain.
