While in Alaska 3 years ago I went to the "musk ox farm". they had scarves, mittens, blankets etc don't know if they make boots but if they do they would certainly be very warm. they say it is 8 times warmer than wool. I am so sorry I did not buy their scarf which is really knit in a circle and you can pull it up over your head to keep warm. Perhaps I can write or email them and still buy one.
