These Merino wool thermal pants are suitable for wear year-round, protecting you from a slight summer night’s chill to frigid winter temperatures. The fibers are naturally non-itching and breathable, and the smooth, lightweight jersey knit is enzyme-washed for extra softness. The wool comes from Rambouillet sheep, descendants of Merino sheep originally from Spain. Adapting to the dry, hot summers and cold winters of the of Montana mountains, they boast a more durable, longer fiber that has greater natural crimp and wave than their Australian or New Zealand counterparts. When spun and knit, the fibers create a natural elasticity and strength that's ideal for performance sportswear - without the need for any added lycra.  The screen-printed, tag-less label on each Duckworth wool garment is a concise synopsis of the story and the mission of the company as a whole: “Grown-Spun-Knit-Sewn-Made in U.S.A.”

Because these pants are made from pure Merino wool, which has natural anti-microbial properties, the garment will not need to be washed as often as other items of clothing. Hand- or machine-wash in cool water with a mild detergent. Hang dry or dry flat. Do not tumble dry.

Launched in September 2014 by co-founders John Helle, Robert Bernthal and Graham Stewart, Duckworth aims to bring the craft of American wool production back to the United States.  They are one of the few—perhaps the only—wool clothing lines to maintain their entire production in the United States, from fiber to finished garment. The raw materials come directly from one of the founders of the label. John, along with the rest of the Helle family, owns a third-generation sheep farm, raising Rambouillet Merino sheep in the mountains of southwestern Montana.
