I used to work at a boutique knitting shop, we sold a lot of types of yarn including alpaca. Alpaca is warmer than sheep's wool because, like polar bear fur, the shafts of alpaca hairs are hollow inside adding another layer of insulation. These will be great for back country skiing before work on -10 mornings. They also fit well and have nice arch support.
