Our hero, Jarvis first brought Merino Wool to Vermont. When it's time to work, the William Jarvis can be your hero, too. This is Merino at its best-”a Full Cushioned sock that provides support and comfort without unwanted weight and bulk that stays cool in the summer and warm in the winter. True Seamless construction makes them irresistibly comfortable. Plus they're anti-microbial and breathable so you can wear them more than once to work and no one will be the wiser. Still made in Vermont. Guaranteed for life.
