In 2004 a family owned company, Darn Tough, started manufacturing socks in Northfield Vermont. In a move that seems crazy, Darn Tough initially gave away 3,500 merino wool socks at the Vermont City Marathon in Burlington. Word of the socks’ durability quickly spread, and outdoor enthusiasts couldn’t stop talking about the lifetime guarantee. 

Darn Tough supports the development of the Responsible Wool Standard (RWS), an emerging international standard that protects animal welfare, provides assurances that farmers follow sustainable land management practices.
