The mountaineering extra cushion sock from Darn Tough has extra heavy terry loop construction that protects the entire foot for maximum warmth. While other extreme cold weather� socks feel more like Moon Boots these socks have a more streamlined performance fit with no slipping, bunching, or 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 an extra day (or two) out of your socks.
