I have a blog update on my favorite gloves for riding in the rain. It's at http://swriding.blogspot.com
I just slip a pair of x-large dishwashing gloves over my regular riding gloves. Got to do that before the leather gloves get wet or it's a struggle. But I don't lose the feel or protection of the leather gloves. The dishwashing gloves are real cheap and orange. I think I got a pair from Aerostich first but they can be found elsewhere.
Personally, if it's not cold, I won't melt.

I love these bikes regardless of what I've needed to fix on them. I'll: Just Ride 'em!
I have "regular" gloves & cold weather gloves, no dishwashers for me as I value my grip on the bar,esp. when wet!
You can't have too much information on rain gloves.
I've tried Marmot ice climbing gloves, diving gloves, mountain bike rain gloves, dishwashing gloves, BMW Summer Rain gloves, and the only thing that's worked for me is Aerostich Triple Digit glove covers.
But I'm looking for some back up rain gloves, so I may give rapz' BMW gloves a try.
