Sheep To Shelf™

American-made, Duckworth is proud to be the world's only source-verified, 100% Montana-grown Merino Wool clothing company.

Our dedicated team carefully manages every step of the process, from raw fiber to finished garment: Knowing Merino Wool is our business.

Starting at our ranch in Dillon, Montana, our open-range Montana Merino sheep live between 5,000’ and 9,500’ elevation and temps ranging from -40 to over 90 degrees Fahrenheit, grazing on natural grasses and Montana wildflowers found on remote mountainsides. The unpredictable and rugged conditions of the Northern Rockies result in a rare Merino Wool: an incredibly soft, yet durable, fiber with exceptional loft and breathability thanks to an unparalleled degree of "crimp" within the fleece.

It's also there, on our ranch, that every single shorn Merino Wool fleece is graded for quality (and thus selected for its end use). Then, we spin those choice fibers into a proprietary yarn: Spinning, knitting, and dyeing is part science and part art, requiring specialized know-how, trusted American partners, and the long-term vision of a fourth-generation ranching family from Montana.

Deep understanding of the manufacturing process allows us to find opportunities for innovation at every stage of development, resulting in breakthrough proprietary wool products and practices, such as our ultralight Vapor Wool and Maverick fabrics, ultra-soft-yet-durable Powder fabric, and our WoolCloud insulation.

Although the U.S. textile industry has been on the decline for decades, with competitors seeking cheaper opportunities oversees, our Sheep to Shelf™ supply chain brings jobs back to small American communities, keeps technical knowledge close to home, and assures maximum life-cycle sustainability.

Duckworth guarantees total supply-chain responsibility, quality, and transparency from beginning to end. That's what Sheep to Shelf™ is all about. That's what 100% Montana-grown and American-made promises every time.

            • A proprietary blend of fine micron Duckworth Montana-grown Merino Wool, cellulose (modal, a recycled bamboo fiber), and recycled Polyester, Vapor Wool produces an ultra-fast-wicking and naturally cooling single jersey fabric. The cooling sensation is due to conductive "revaporation," which kicks in during any form of physical exertion.

            • Named after Maverick Mountain in Montana’s Beaverhead range (and the rule-defying outdoor athletes that rock these expedition-grade fabrics), Maverick and Maverick Peak are real-deal 100% Merino Wool baselayers - the epitome of Sheep to Shelf™. Both Maverick and Maverick Peak boast an ultra-soft jersey fabric with all natural stretch, (AKA no added lycra or polymers, just pure and natural wool grown in Montana). Added bonus: The natural antimicrobial profile of Merino Wool means any Merino-based apparel requires infrequent washing and will not stink.

            • First invented in 1912 by J. E. Morgan ("Long John" Morgan), the waffle knit traps dry air in huge air pockets against the skin, creating a buffer that regulated core comfort with unparalleled results. For the first time since its inception, Duckworth has re-imagined this world-famous knit using Merino Wool, dubbed Polaris. We don't mean to brag, but Polaris is quite possibly the world's lightest, warmest fabric. Ever. Period. Full stop.

            • Named after a jagged, rock-covered mountain in Montana's Beaverhead Range, Comet is for those heavyweight baselayer needs. Ultra-durable Comet boasts a natural-technical mash-up, combining a pure, 100% Montana-grown Merino Wool outer layer and a recycled polyester inner layer. Why the combo? Polyester is hydrophobic, meaning it will wick sweat and moisture right off your skin and into the hydrophilic wool layer. It gets better: wool chemically begins to get even warmer when introduced to water and water vapor, adding a whole new degree of heat to Comet's high-tech performance.

            • Our Powder line, perfected in the high-altitude mountain ranges of Western Montana, is the pinnacle of cozy baselayer goodness. Featuring an engineered Merino Wool fleece composition and a brushed-soft liner for direct-to-skin comfort, Powder is the uncontested champion of Merino Wool mid-layers, wicking moisture, trapping heat, and staying oh-so-soft.

            • Shockingly light and with a high breathability factor, WoolCloud's "wool batting" filling holds its warmth and shape better than any down (read: plucked bird feathers) or synthetic jacket filler, and is completely renewable to boot. By using thicker Merino Wool fibers that are not choice for fine, next-to-skin garments, we are able to maximize the effectiveness of course wool's incredible insulating properties without letting any of our shorn wool go to waste. A water- and wind-resistant exterior and lining make WoolCloud a must have for any foul weather conditions.
