Montana grown, USA spun, knit and sewn. Duckworth is a Montana source-verified wool company. We use 100% Helle Rambouillet merino, grown in a natural environment, raised on mountain pasture, and processed and built 100% in the USA. Open Range Wool - at 9500’ elevation, the specific conditions of the Montana Rockies grow the world’s best wool. Source-Verified - this is a key difference between Duckworth and all wool brands sourced outside of the USA. We make our own goods from our own Helle Rambouillet merino, we don’t source them. At Duckworth, knowing and using what’s in our own backyard is what really counts. 100% Made in USA – Grown in Montana, our wool fibers travel to the Carolinas for spinning, knitting and sewing to our strict standards, creating an impeccable final product. #SheeptoShelf (less)
