Smartwool apparel and socks

Smartwool is an American brand that revolutionized the outdoor industry by introducing Merino wool performance socks in the early 1990s. The brand was founded in Steamboat Springs, Colorado, by ski instructors who wanted a wool sock that didn't itch and kept feet warm and dry. Since then, the product line has expanded to include base layers, mid-layers, and accessories designed for high-performance outdoor activities.

While originally an independent company, Smartwool has undergone several acquisitions and is currently a key brand within a major global apparel conglomerate. Manufacturing remains heavily focused in the United States, particularly for its core sock lines, though global supply chains are utilized for other technical garments. As of 2026, the brand continues to operate under the ownership of VF Corporation, maintaining its commitment to sustainable sourcing and high-quality Merino wool materials.
