Men's and women's socks are knit in a durable and warm-yet-breathable merino wool blend. These socks naturally regulate temperature, wick moisture, and feel soft against the skin. Reinforced heels and toes add durability for daily wear, while a cushioned footbed provides all-day support—perfect for everything from trail days to everyday routines. • 52% Nylon/45% Merino Wool/2% Spandex/1% Polyester • Made in USA Fabric Care • Machine wash, warm • Turn inside out • No bleach • Tumble dry low
