Darn Tough

It's a brand uniquely created around a single, fine gauge needle, which means all Darn Tough socks, from their Mesh running sock, to their over-the-calf Full Cushion ski sock is crafted with the same high quality raw material and high density knitting techniques that make their product unique. In an era of outsourcing and corporate take overs, Darn Tough is still true to their roots. Family owned and run, in Vermont, since 1978. In a word, local. Their experience is their reputation and Darn Tough backs it up with their lifetime guarantee. If their All Weather Performance Socks aren't the most comfortable and durable socks you've ever owned, return them for your money back."As Darn Tough likes to say, "We know socks, we wear 'em year 'round."™
