Darn Tough, a brand of Cabot Hosiery Mills, was created in 2004 in Northfield, Vermont--the perfect testing ground for the finest all-weather performance socks. There, company employees field test Darn Tough while biking, running, hiking, snowboarding, and skiing in the most challenging, even unforgiving, weather conditions in the contiguous United States. Cabot Hosiery Mills has been making textiles since 1978, always in Vermont. Every Darn Tough sock is knitted there. After all, as the company’s CEO once stated, “nobody ever outsourced anything for quality.” And that’s what you can always count on with Darn Tough socks: quality. Darn Tough’s company credo is that they have yet to produce their best sock. That pursuit of excellence, that unflagging commitment to quality, comfort, durability and a perfect fit shows in every pair. That’s not an empty corporate motto: Darn Tough guarantees its socks for life. No conditions. No strings.
