I don't believe there is such a thing a breathable shell where you won't sweat to death when you're riding.

I have a couple of tops with Windblocker in the front. One from Ground Effect and the rest of it is wool. One from Patagonia and the rest of it is fleece. I like these a lot because they do keep my core warm, but the wool and fleece allow my sweat to dissipate as I ride.
