The SmartWool Hunt Medium Crew Sock is perfect for long days outside in cooler weather. The SmartWool Fit System offers excellent arch and ankle support, while the flat-knit toe seam allows the foot and sock to flex without bunching. The medium, full-cushioned leg and foot offer superior impact absorption for long-wearing comfort. The crew-height sock is made from a durable blend of 66% Merino wool, 33% nylon, and 1% elastane fabric. Made in the USA.
