The Ultimate EXTREME THICK THERMAL Sock provides greater thickness and durability for cold climates with 68% Alpaca. Let Alpaca show off its phenomenal insulating property so you can enjoy your outdoor activity. Reinforcement is on the heel and toes, is machine washable and is so soft.
I designed these socks to be softer, added more terry length for even more cushy comfort and they are not as tight on the calf as the past favored Extreme socks that I redesigned. Of course there is extra heal and toe reinforcement as in all of my socks.
