A true classic and a longtime favorite with serious hikers and everyday enthusiasts alike. Full Cushioning throughout this entire sock provides support and comfort without unwanted weight and bulk. Coveted for its dependability and comfort this sock has a smooth performance fit that you won't find in the other guy's full cushioned socks. No slipping, no bunching, no blisters. Fine gauge Merino Wool makes this a fast drying and breathable "all-weather" sock that stays cool in the summer and warm in the winter. 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. Still made in Vermont. Guaranteed for life.
