Duckworth - Montana Grown Merino Wool. 100% Made in USA.

OPEN RANGE & SOURCE-VERIFIED

Sheep to Shelf

We don’t source wool, we grow it on our ranch in Montana. We carefully manage every step of the process, from fiber to finished garment. Wool spinning, knitting and dying is part science and part art, requiring specialized know-how and total supply chain responsibility, quality and transparency from beginning to end.

Source-Verified

Duckworth is a source-verified merino wool company.
Trust, quality and comfort are paramount, assured by the pedigree of our wool supply from the Helle Rambouillet ranch and other certified Montana wool growers.

100% Made in USA

Wool made in the country of origin – The United States – creates value added product for our local economies and brings jobs back home. Keeping wool science and knowledge at home inspires technology and innovation at every level of the process, building a vibrant and globally competitive textile industry for the long term – Resurrecting the lost art and craft of American wool is our mission.
