The hollow, moisture-wicking fibers from Darn Tough's 100% recycled THERMOLITE® ECOMADE materials trap heat and insulate feet with a soft, dry layer that protects you from hot spots, holey socks, and the need for frequent visits to the lodge to thaw out.
Machine wash in warm water on gentle cycle with socks inside-out. Do not bleach. Tumble dry on low or hang dry. Do not dry clean.
