Very warm over calf socks for winter mountaineering. Extra heavy terry loop construction protects the entire foot for maximum warmth. While other extreme cold weather socks can feel more like Moon Boots these have a streamlined performance fit that keeps up with you in the worst of weather. No slipping, no bunching, no blisters.
Fine gauge Merino Wool makes this a fast drying, breathable sock that stays warm in the winter and amazingly cool in the summer. And since Merino Wool is naturally antimicrobial this sock repels bacteria and odour - a great feature when you need to get any extra day (or two) out of your socks.
77% Merino Wool, 19% Nylon, 4% Lycra® Spandex.
