TR I've been working at various 350-400 weight merino. I love merino but it takes a while to dry when I sweat. I've not heard of alpaca socks. I have issues with cold feet, I doubt theyll be too warm for me <G>
I just looked, I have a heavyweight FL layer called Labrador. I don't think they make it anymore. It's full zip and heavy duty. You are right, it doesn't deal well with getting wet.
I also bought 2 sizes too small and it fits me fine. Kinda strange sizing.
