The Liner Crew Wool is the ultimate baselayer sock for your hiking and trekking adventures. By wrapping each toe in Merino wool, this sock prevents blister-causing skin-on-skin friction and keeps your feet comfortable and dry by wicking moisture away from your skin. Layer the Liner Crew Wool with an outer sock for added cushion and protection, or wear it solo as a soft, lightweight day-hike option. Made from 74% merino wool, 22% nylon, 4% lycra
