I kinda like slabs in the rain when all the gear is working right. Back roads not as much with the slippin' & slidin'.
Back when I had a lucrative career, I bought 4 or 5 different "motorcycle" designated rain suits. I couldn't get with the Frog Tog heavy paper thing. Felt like wearing a Tyvek house wrap. My Frog Tog suit went to work with me and now looks like Rag Tag. That's nothing to do with the quality, just long term abuse. If that "I'm wearing a frikkin cardboard box" thing doesn't bother you, then Frog Togs are probably just the ticket. It drove me koo koo.
My favorite - a Walmart $20 2 piece suit made by a famous maker whose name I forget at the moment. It packs very small, and works very well. It's a lined nylon thing. Their (discontinued around here) $20 motorcycle covers were awesome too. If anyone can still get these covers, I'd be much obliged if you'd send me one...
New favorite rain pants - Cabelas pack light Gore Tex pants. They work very well, and pack extremely small, around the size of an empty paper towel tube or smaller. I paid half price from the Bargain Cave. Doubt I would have paid full retail. Cabelas pricing is usually too high for my cheapniss ways. Their site is down at the moment, but if anyone is interested, I think they call this style pack light or pac lite or something like that?
Daughter gave me a Helly Hanson rain coat for Christmas. To her extensive dismay, I insisted upon orange. She felt that was dorky, but I am, after all, a dork, and proud of it. It's a good coat, but man are they over priced. I think it was $80 for a plastic rain coat.

http://www.webbikeworld.com/motorcycle-boots/treds-rain-boots/I invested in a pair. They are awesome, and go to work with me too. Very light in weight, but also very durable and flexible. Worth the high price if y'ask me. They don't pack too well. I bet the Aerostitch overboots are excellent too.
I think it was Moe or Glazer who once said "There's no such thing as breathable rain gear." I spend a lot of time humping a snow blower and shovel all Winter at work, and I would have to agree with this statement. I can manage the sweat with high performance base layers, but the rain coat ain't breathing very much - that's for dang sure.
