What to know about Darn Tough
Lifetime guarantee, no receipt logic
Every pair carries an unconditional lifetime guarantee: wear a hole in them and you get a free replacement pair, which is the brand's main argument at this price.
Knit in its own mill
All socks are made at Cabot Hosiery Mills in Northfield, Vermont, the family contract-knitting business Ric Cabot took over in 2004 and still owns independently.
One product, many use cases
The line is socks only, split across hiking, ski, running, work, tactical and everyday styles in merino and synthetic blends, including US military contract pairs.
