Woolpower Socks Classic 400

Woolpower is a renowned Swedish textile company that specializes in thermal undergarments and socks designed for extreme weather conditions. Founded in 1969 in Östersund, Sweden, the brand originally operated under the name Ullfrotté, which is also the name of the patented material it uses. This unique fabric—composed of merino wool and synthetic fibers—is knitted into a terry loop structure to trap air and provide maximum insulation while wicking moisture away from the skin.

What sets Woolpower apart is its commitment to high-quality craftsmanship and local production. Every single garment is produced at the company's own factory in Östersund, Sweden. The brand follows a unique production philosophy where each item is sewn from start to finish by a single seamstress, who then signs the product with a name tag. This ensures total accountability and a personal touch for every piece of apparel that leaves the factory.

The brand remains a family-owned enterprise under the umbrella of Ekstigen AB. This ownership structure has allowed Woolpower to maintain its focus on sustainability, ethical labor practices, and long-term quality over mass-market quantities. The brand is a major supplier to the Swedish and specialized military forces worldwide, as well as outdoor enthusiasts who prioritize authentic Swedish manufacturing.
