The Wander Liner Sock is crafted from a soft synthetic fabric that efficiently wicks away moisture and reduces friction, helping to prevent chafing on long hikes. It’s designed to work perfectly as a liner under a warmer sock, but can just as easily be worn on its own when you want a light, thin sock for everyday use or warm-weather activities. Wander Liner Sock is a versatile essential for anyone looking to keep their feet happy mile after mile.
