Mountaineering Over-the-Calf Heavyweight Sock Men's

Sleet, freezing rain, snow? Keep it comin’. This Mountaineering sock simply doesn’t back down. Extra heavy terry loop construction protects the entire foot for maximum warmth. 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 odor – a great feature when you need to get any extra day (or two) out of your socks.
