For many years we’ve prioritized the use of Merino wool exclusively from sheep that have not been exposed to the practice of mulesing. A performance fit means no slipping, no bunching, no excuses. Darn Tough socks are the most comfortable and durable socks you'll ever own. We’ve prioritized Merino wool throughout our product lines and our goal of producing the most responsibly made product is reflected in our commitment to the success of the Responsible Wool Standard. ONE MISSION - Darn Tough is a family-owned, American manufacturer of end-use-specific socks. To date, nylons generated from pre-consumer waste material have held up well against our durability requirements, but we’d like to find an equally good source of post-consumer recycled nylon or yarns that blend both pre and post-consumer nylon. As you’d expect, we are actively investigating and testing new fibers and yarn blends that do not appear in our current products. Our backyard is the perfect testing ground to make the finest Premium All Weather Performance Socks. Stay warm and dry even in the harshest winter conditions. Today, 100% of the wool we procure is RWS-certified. While spandex accounts for no more than 5% of the fiber used in our finished product, it represented 27% of the raw materials we procured last year. In short, using recycled nylon conserves energy and water and reduces greenhouse gas emissions from manufacturing. RECYCLED NYLON We use REPREVE, a nylon 6 fiber made from pre-consumer industrial waste that would otherwise be landfilled or downcycled. While we aim to reduce our use of virgin nylon in our products, recycled nylon only accounted for 4% of our nylon consumption last year. We do it because for us, it’s the only way to do it. This leads to a more comfortable, durable, great fitting sock with no added bulk. Darn Tough | Socks for Winter - Christy Sports OVER-THE-CALF HEIGHT Over the calf: the name says it all.

MATERIALS IN OUR SOCKS Every material we use in our socks has been carefully chosen and tested to meet our rigorous durability standards. MERINO WOOL Merino wool is the most important and relied upon fiber in our products and accounted for 56% of our yarn consumption by weight last year. Although the market share for RWS is only estimated at ~1% of global wool production, the number of certified sources has grown substantially over the last couple years. Our all-season weight, midweight socks thermoregulate to wrap feet in steady comfort when temperatures change. Unfortunately, it’s the most difficult material in our fiber mix to replace with a recycled alternative. The ultimate height for keeping the outside, out. ONE FAMILY - We are family owned.
