Founded in 1994 by Steamboat, Colorado ski instructors, Smartwool's first merino wool socks were the warm answer to cold feet for winters spent in the Rocky Mountains. A quarter-century later, Smartwool socks and apparel remain solutions to cold, sweaty, and stinky garments in any outdoor setting. From Smartwool baselayers and tights, to underwear and beanies, the brand is dedicated to creating clothing and accessories through innovative merino wool designs. Temperature regulating and moisture-wicking collections, including Smartwool ski socks, are perfect for runners, hikers, climbers, and winter sports lovers. They also source their high-quality wool from the non-mulesing New Zealand Merino Company. Don’t sweat your sweat with the best merino wool products from Smartwool.
