About Darn Tough

Darn Tough started making socks in Northfield, Vermont over 30 years ago. Frigid winters and humid summers imparted the wisdom that not all socks are created equally. When living in the most unforgiving climates, you need a pair of socks that are tough and also keep you dry and warm. Whether you’re skiing, hiking, biking, climbing, or running, these socks are impervious to the elements.

The Darn Tough team spent over a year testing yarn combos and different designs, confident that eventually a unique and special product would result; a sock that could be guaranteed for life. Never outsourced, never compromised, Darn Tough Vermont is a purely American business that has been going strong for generations.

Over the last seven years, Darn Tough has worked intimately with key members of the U.S. Armed Forces to develop a sock that would provide an immediate improvement to work in the field. You need to focus on your mission instead of your feet. These socks are consistently chosen by servicemembers from all branches of the military, and they’re proven under the most strenuous conditions in the field.

The Tactical line of footwear includes the Tactical Boot, Tactical Dress and Tactical PT socks, which comprise 23 different styles. Choose from the True-Seamless™ mesh, no-show PT socks to over-the-calf Extreme Cold Weather Mountaineering Boot socks. Additionally, Darn Tough Vermont offers one of the largest selections of Berry Amendment Compliant socks in the tactical industry. Whatever your mission-specific requirement is, GovX has your Darn Tough military discount.

What Makes Our Socks Tough

We live and work in Vermont. Our backyard is the perfect testing ground to make the finest Premium All Weather Performance Socks. We ski, snowboard, hike, bike and run in the most unforgiving climate in the lower 48. It is under these conditions that we design, test and manufacture our socks.

High Density Knitting

More knit stitches per inch equates to durability and cushioning without bulk.

Performance Fit

From form fitting toe boxes to sculpted heel pockets and knit-in elastic support at the arch, our knitting techniques produce the finest fitting performance sock available.

Merino Wool

Our custom count, shrink treated Merino wool enhances the comfort and durability that outdoor enthusiasts have come to expect from this fiber.


Because wool is not for everyone. We use an exclusive Coolmax® blend to create a sock with exceptional softness, durability and superior moisture management.

Ribbed Knit

Form fitting to the contours of your calf, shin and ankle ensuring a custom fit.

Ribbed Ankle Support

No Slipping. No Bunching. Helps prevent blisters.

Elastic Arch Support

Knit into the arch of all of our socks to provide added endurance.

Ring Toe Construction

Terry loops surrounding the toe create a comfortable invisible seam.

All of our socks are Guaranteed For Life—no questions asked!
