Alpaca Sock - Survival Over-the-Calf Heavyweight

Meet the sock that doesn’t quit before you do. The Survival Over-The-Calf Alpaca Sock is designed for long days, harsh weather, and serious mileage on foot.

Heavy-weight, fully cushioned, and climbing several inches higher than a standard boot sock, it delivers maximum coverage and warmth from toe to just below the knee.

Alpaca’s natural insulating power keeps feet comfortably warm without getting clammy, while the dense terry loop interior traps heat and channels moisture away from the skin. Whether you are breaking trail in deep snow, glassing on a windy ridge, or working outdoors from dawn to dark, this is the sock to reach for when conditions are at their toughest.
