Welcome to the Birthplace of Your Duckworth Wool Baselayer

Earlier this month, the Helle Rambouillet Ranch, a fourth-generation family sheep operation on 25,000 acres outside Dillon, Montana, held its annual shearing. Photographer David Stubbs captured the action as highly skilled workers took more than seven tons of raw Rambouillet wool off the animals. That wool will soon be cleaned, combed, spun, knitted, dyed, finished, cut, and turned into sweaters, jackets, baselayers, hats, and other products for boutique U.S. wool apparel maker Duckworth.

Lanolin, the natural wax secreted by wool bearing animals, greases the floors of shearing sheds, so shearers have to wear special moccasins with a non-slip coating for solid footing.
