I've been impressed with the Marmot Super Mica, and I'm not alone; Backpacker.com had it as an editor's choice at some point, I believe.
It's a raincoat, but it's so thin and the material is so... intriguing, I find it doesn't heat up like other raincoats I've used in the past. It breathes very well, but the nature of the material seems to cut the wind. My experience may be different from your own, but I have been very happy to have this item serve both roles.
I will say, however, you get about 30 minutes in the rain before it wets out. I use raincoats to fix my tent, not hike in. if it downpours, I count on Merino Wool to keep me warm when wet or I get out of the rain and underneath a tree.
My rain system is also not yet perfect, though...
