This hiking staple is celebrating its anniversary as a well-rounded sock for performance and everyday wear. Darn Tough makes socks with the durability to last for years, and this pair is no exception. The merino wool construction is built to last with materials that naturally fight odor, regulate temperature, and wick moisture while we're active. These socks are knit with a light cushion that increases comfort and prevents blistering during long days on the trail.
