Pair these lightweight hiking socks with a stripped-down pack and some awe-inspiring terrain. They feature variable-knit construction under the mid-foot and arch to disperse heat and cushion hard knocks. A new trio of fibers improves moisture control and airflow: merino wool (100% chlorine-free) for soft comfort and life-of-the-sock cushioning, nylon for trail durability and polyester to wick away moisture. These fibers are "sandwiched" together to bolster skin comfort and durability. The seamless Lintoe® construction adds nonchafing solace to trail-weary toes. Made in USA.
