I'm looking for a waterproof, LIGHT WEIGHT, rain jacket that will fit under my seat. I've got the DP gel seat. Anyone own or know of such a jacket? I'm tired of lugging around my full rain suit. Been checking on ultralight jackets from REI, but most have hoods. Thanks!

fox makes a clear rain jacket. Wont fit under a seat. Thick enough not to tear like a garbage bag. Sells for about $25.

frogg toggs (specifically the road toad model) makes a suit that fits in a small package; not sure if it will fit under the seat though.  Come to think of it, I don't imagine any suit will fit under there.  I could be wrong.

I  bundle mine up and use velcro straps to secure it to my trellis frame. Don't even know it's there when I ride, and I got it when it gets wet
