Smartwool

PhD Outdoor Light Crew Sock

Make sure your feet are comfy while you take in the beauty and grandeur or our National Parks with the Smartwool PhD Outdoor Light Crew sock: Charley Harper National Park Poster Bird on a Mountain. This hiking-focused sock sports a graphic based on the late, great Charley Harper's iconic artwork. Merino wool regulates temperature to offer comfort whether it's hot or cold outside, and the 4 Degree Elite fit system provides excellent stretch and recovery. Mesh ventilation zones allow cooling airflow when you're walking under the harsh desert sun in Arches National Park, and the flat toe seam won't cause blisters or uncomfortable pressure points during long treks through Yosemite.
