First. Never finished. They invented the first Merino wool performance sock, but they'll never stop trying to make it better. Their Classic Hike socks are getting upgraded and it starts with recycled nylon. Their first-ever Merino wool hiking socks are now made more sustainably than ever before. Light cushioning on the bottom of the sock and ZQ-certified Merino wool offers comfort and natural performance benefits that help take care of your feet on every hike. With new patterns and the same all-day comfort, their oldest (and best) women's Merino hike sock may be your new favorite.
