Designed for extended cold weather activities in extreme environments. This is the cutting edge of warmth technology!
Based on feedback we received from professional mountaineers and cold-weather athletes we learned that most wool socks on the market were too constrictive and maintained moisture during their activities. This can be dangerous in parts of the world where a wet foot can lead to hypothermia or other serious conditions. Our design team wanted to solve this problem by creating a sock that would be incredible warm and dry. We searched the globe to find materials and a construction process that provide the perfect combination of elasticity, support, and warmth.
Two Layers of Polartec® Power Stretch on the outer layer of the sock provide warmth without increasing weight. The smooth outer layer is wind- and abrasion-resistant; the soft inner layer pulls moisture away from your skin keeping you dry, warm and comfortable.
A layer Polartec® Power Dry® keeps your skin dry when you sweat. Features a patented bi-component knit construction that uses different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly.
Special sizing applies to these socks. Please check sizing chart below.
