Agreed. I have lots of merino wool base & mid-layers, and it's very comfortable when wet, although a bit heavier. I have a Gore-Tex Active outer shell, but I still sweat when wearing it. I've yet to find any waterproof that keeps you dry from inside when exericsing, so having a comfy base layer is really importnat.
