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.


Trekking Expedition Polar Tec Crew

Designed for extended cold weather activities in extreme environments, this sock uses cutting edge warmth technology. Featuring two layers of Polartec power stretch fabric sandwiching prim aloft footwear insulation in a left and right anatomical shape these technical socks will protect your feet in the most extreme conditions. This fabric compilation allows natural movement and extreme protection. A layer of Polartec power dry with antibacterial properties keeps your skin dry when you sweat and wicks away moisture to leave your skin dry and blister free. This sock 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. The smooth outer layer is wind and abrasion resistant further protecting your feet in extreme conditions. The Polartec crew socks also include heavy cushioning on the sole and shin area, offering superior comfort and added insulation. These socks are a great choice for extreme protection on cold weather hikes and adventures or for snow and ski trips. Tested above 8000 meters these socks are as good as it gets.
