My husband and I icefish in the Upper Peninsula area of northern Michigan. At times we are exposed to temps of -50 degrees. Along with a great pair of Micky Boots, these socks are not only comfortable and dry but odor free...yes, I said ODOR FREE! I've had the Targhee socks for 3 years now and they still hold their shape and performance perfectly. I need 10 more pair to get me through retirement! Most favorite sock by far.
