My Marmot DriClime wind jacket has vented armpits. My Patagonia hooded rain jacket has zippered armpits. Neither suffer from ventilation problems that result in getting clammy, so maybe these design features are the key to synthetics.
They both block wind and rain in a way which no woolen material in my wardrobe can approach, and at about a quarter of the bulk and weight. I bought a cheapo transparent emergency rain top with no ventilation from Nashbar some years ago. It fogs up with condensation, sweat running down the sleeves in torrents inside of 30 minutes, irrespective of base layer material.
