Over 25 years ago, we invented the original Merino wool performance sock-the Classic Hike. The Classic Hike remains mostly unchanged and certainly unmatched in comfort. But today, it's getting upgraded. And that upgrade starts with recycled nylon-adding more sustainability to our favorite socks. They're also made with responsibly sourced, ZQ-certified wool that was grown with a focus on ensuring environmental, social, and economic sustainability while also taking the best care of our Merino sheep. This is a women's cozy, capable classic that is never going out of style.
