Thorlo's Unisex TKX Trekking Socks are constructed with a blend of Thor-Lon acrylic and Wool to deliver extra warmth, and serious impact-protection. When your mountaineering or trek hike takes you above the timberline, Thorlo's TKX crew sock is up to the job. The TKX boasts effective moisture-wicking, while added cushioned instep and arch ensure more comfortable wear. The TKX's low-profile toe seam won't dig or rub, and added vent panels mean your foot will not overheat. The TKX Unisex Trekking sock is proudly made in the USA.
