I have been using my Mountain Hardware Alchemy lately for when I'm on the bike. And it works great for when it is chilly out. But, there are times when the temp is high enough that the Alchemy is too warm, but without it I'm too cold. Sometimes it is a simple windchill that gets to me. So I'd like some recommendations on what I should be looking for, that will be cooler than the Alchemy, yet block the wind well enough to keep me from getting cold.
