Bw-in 10-35 degrees I typically wear merino t-shirt, FL Chama hoody and then a 350 WT wool zip up. If I need to dump heat, I can zip open that heavy weight. Keep a puffy in the bag for sitting.
I have limited knowledge of alpaca, but several years ago got a pair of alpaca socks as a gift. They are too warm. I couldn't imagine hiking in those. Now, they are thick, heavy socks....a lighter weight version maybe better?
