America’s heritage will keep you warm.

Compared to wool, bison down is warmer, better for moisture control, more durable and easier to care for. The major challenges of using bison down are it’s short staple (length of fiber) and exorbitant cost - some of the reasons why you don’t see it used more often.

Despite the challenges, UBB has spent the last year developing the yarn and have now created a sock that is technically sound, commercially viable, and fully made in America. The brand has put together a supply chain of ranchers out west, yarn spinners in the east, and a sock knitter in the Midwest to deliver a high quality sock that is responsibly made and durable.

Once the yarns have been spun they are carefully knit into a sock that’s engineered with a flat toe seam, reinforced heel, and padding for support. The Ultimate American Sock is built for comfort and durability. The final product comes packaged in a box made in Wisconsin. The story of the sock and its journey through America is an integral part of the package's design.

By purchasing this item, you help UBB remove 1 pound of trash from our oceans and waterways around the world.
