Circle Wool
In an effort to shift toward circular design and systems thinking and to take responsibility for the waste we produce, our fabric research and development, sustainability, and production teams collaborated with factory and mill partners to create a fabric made with repurposed wool Theory scraps and recycled wool.
Sourcing + Sorting
In partnership with a factory which produces select Theory outerwear styles, our design team collected wool scraps from the Fall 2022 collection’s cutting process. Transported to the Manteco mill in Prato, Italy—winner of the 2023 Climate Action Award—these scraps were mechanically detangled in a chemical-free process.
Color Development + Recycling
Once carded, these fibers are combined with Manteco’s MWool® recycled fibers and polyamide using the mill’s exclusive Recype® process. Specific percentages of each fiber are blended to achieve a rich charcoal melange hue without water, dyes, and added chemicals. This blend is then twisted to create a durable yarn which is woven into a new fabric.
The Impact
Across the fashion industry, up to 20% of fabric is left on the cutting floor and wasted during the manufacturing process. Manteco’s proprietary method allows us to transform cutting scraps into new fabric while reducing our environmental footprint.
Good Wool
Our Good Wool is sourced from responsible farms in Australia and woven by an eco-conscious mill in Biella, Italy.
The Farm
Good Wool begins with free-roaming merino sheep at farms like the Beaufront farm in Tasmania, Australia, which follows strict land management and environmental conservation programs. This non-mulesing farm shears its sheep with the utmost care and preserves native grasslands with strategic grazing practices.
The Mill
Good Wool is woven at the Tollegno 1900 mill in Biella, Italy, which self-produces 35% of its energy using solar panels and water turbines powered by the neighboring Cervo river. All alpine water used to dye and finish Good Wool is purified and returned to its source, while 40% is reused.
The Atelier
After it’s expertly finished in Biella, Good Wool arrives at our atelier and innovation center in Manhattan’s Meatpacking District. Prized for its lightness and smooth hand feel, Good Wool is carefully tailored into prototypes of our blazers, trousers, and more.

Good Cotton
Good Cotton is crafted with extra long staple SUPIMA® cotton. We’ve partnered with Oritain,a company that uses forensic science to verify our cotton fibers from the farm to the factory in Italy.
.
The Farm
Less than 1% of the world’s cotton crop is SUPIMA®. Ours is grown on farms in Southwestern and Western United States like the Boswell farm in California which practices precision agriculture—a technique that maximizes output and quality while minimizing resource usage. These farms rotate between cotton and food crops to maintain the health of the land.
The Mill
A fifth generation family business, the Albini mill in Bergamo, Italy has reduced its annual energy usage by 8,000,000 kWh, which is equivalent to powering 2,700 households for an entire year. The mill's annual water consumption has been cut by 46,000 m3, which is enough to fill 18 Olympic size swimming pools.
The Atelier
Transported to our atelier and innovation center in Manhattan’s Meatpacking District, Good Cotton is tailored into the intentionally designed prototypes of shirts and dresses that are known for their crisp look, subtle stretch, and year-round appeal.
Good Linen
Woven exclusively for Theory by the Marini & Cecconi Mill in Prato, Italy for 25 years, Good Linen is crafted with three fibers: linen sourced from France, viscose created from waste cotton fibers, and recycled elastane.
.
The Farms
Good Linen continues a centuries-long agricultural tradition that requires little water and provides natural soil fertilization. Made from the fibers of the flax plant, our linen is sourced from five farms in France’s Normandy region all of which are federated under The Alliance for European Flax-Linen & Hemp. These farms take a zero-waste approach to flax production, putting every part of the plant to use—from the seeds which are pressed for oil to the stem used to make particleboard.
The Mill
Family owned and operated since 1945, the Marini & Cecconi Mill is one of the first signatories of the Greenpeace Detox Program geared towards removing hazardous chemicals from the production process. 50% of the water used in the production process is recycled thanks to GIDA, a special water purification system in Prato. The company also uses electricity generated from a photovoltaic system which converts thermal energy into electricity.
The Atelier
After receiving Good Linen from Prato, our atelier and innovation center in Manhattan’s Meatpacking District skillfully crafts the initial prototypes of our garments. Used in a wide range of silhouettes from blazers and trousers to dresses and tops, this airy, light fabric is preferred for its excellent stretch and recovery.
