Alright, that is pretty neat.

I used Speiwak rain gear for a while. Bit large for me these days, but it is pretty tough stuff with oversized pockets and super secure seals. Meant for military use. However, I've come to enjoy sweating less than getting soaked, so I only use a light water resistant jacket - holds up well enough in moderate rain. Really, a change of clothes is more useful than a rain jacket in any case.

I also carry two of something like this: Amazon.com : Emergency Poncho, Emergency Rain Gear, Weather Protection, Emergency ZoneŽ Brand : Camping First Aid And Safety Equipment : Sports & Outdoors

Mostly as a just in case; a pair fits perfectly in one smaller pocket of my trunk bag and they weigh nothing. I presume I'll likely end up giving them away to someone caught in a rain more than I'll use them, though.
