The Wigwam Merino Comfort Explorer Socks are the heavyweight version of Wigwam's bestselling Merino Comfort Hiker socks (Style F2322), with American-grown and super-soft Merino wool. Thick enough to cushion and keep you warm even on chilly nights, the Merino Comfort Explorer is perfect for early Spring and late Fall hikes. Merino wool can absorb 33% of its weight in water before it gets damp or starts to sap your warmth — and energy. And all that premium, insulating Merino wool means the Explorer is one of the most comfortable socks we've seen. When you're going off into the backcountry, "kind of cold" feet that are "kind of dry" just won't cut it. Pick up a pair of the Explorers for your next hike, so we don't have to remind you that, "we warned you". Formerly known as the Blue Ox Socks.
