The Original

Merino Wool Sock

In 1994, we invented the first-ever Merino wool sock—the Classic Hike. They are our origin story. The catalyst. The beginning. And inspired wannabes worldwide by setting the standard of Merino wool performance socks. Almost 30 years later, these socks remain mostly unchanged and still an icon in the outdoor community.
