Merino wool is expensive but amazing. I got a polar fleece base layer and poly layer at CT and they work well. I will tell you the best secret I know as far as cold weather goes; go with wool socks and as many thin layers as possible. Air gets caught between the layers and insulates while weighing almost nothing. also if you are going to sit, walk in in as little clothing as possible then put it on when you get there so you don't sweat up your clothes. Last thing no cotton.
