"I'm Going to Send You 21 Pair": Warranty Letters Video

At Darn Tough, every sock is backed by an Unconditional Lifetime Guarantee — if you wear out our socks, we’ll replace them. It’s that simple.

Most warranty claims are for a pair or two. This guy had, oh, just a few more. And he included a note:

"I have been a full-time professor and outdoor and climbing program director for the past 21 years at Calvin University. I have been a 20-year representative and advocate of Darn Tough socks.

"I have over 500 students per year on overnight trips, and two to three pair of Darn Tough socks are on the required packing list for every overnight backpacking trip. I tell students that there is no equal.

"Darn Tough socks are the only ones I use. This goes for my wife and our four children as well."

Two decades of putting our socks through their paces. We were founded in 2004, 22 years ago… safe to say, he’s on OG Darn Tough wearer.

"I'm going to send you 21 pair. I will let you use your discretion, but some replacements would be appreciated. Thanks for your consideration."

When someone tells hundreds of students every year that "there is no equal" ... We don't take that lightly. And we do cover that.

Thanks for the note. And thanks for taking us along on the journey.
