The Smartwool story starts in the heart of the Colorado Rockies. At the heart of their products is the highest quality Merino yarn available, from sheep raised in some of the most amazing places on earth. Places like the beautiful ranches of New Zealand and Uruguay. The timeless craftsmanship found in the American Southeast skillfully transforms fiber to form, ultimately making the world’s best performance socks, right here in America. Smartwool performance and casual socks made in the USA start with the world’s finest Merino. Then the best designers and skilled craftsman bring them to life, creating extraordinarily comfortable socks. They have been knitting American-made socks since Smartwool started over 20 years ago and their multi-generational sock makers know what it takes to make the best socks.
