Grown from the earth or raised on it. Every fiber below qualifies under our natural standard — here is what each one is, where it comes from, and what makes it worth wearing.
Plant Fiber
The world's most cultivated natural fiber, cotton grows within the seed pods of the cotton plant. From everyday standard cotton to rare certified varieties prized for their exceptional fineness and softness, quality varies significantly by staple length and growing practice.
A cellulose fiber harvested from the seed pods of the cotton plant, with staple lengths typically ranging from 0.75 to 1.25 inches. The longer the staple, the finer and stronger the resulting yarn. Soft, breathable, and highly absorbent, cotton is as versatile as any fiber in existence and has shaped global trade for centuries.
Grown without synthetic pesticides, chemical fertilizers, or transgenic seed technology. Organic cotton follows certified farming standards that promote biodiversity and ecological balance. The fiber itself is identical in quality to conventional cotton, but the difference is entirely in how it is grown, and the absence of synthetic chemicals throughout the supply chain.
A premium extra-long staple (ELS) cotton with fibers measuring 1.4 inches or longer, substantially longer than standard cotton. The extended staple length produces a smoother, stronger yarn with natural luster and exceptional resistance to pilling and tearing. Named after the Pima Native Americans who helped cultivate it, Pima cotton is grown primarily in the southwestern US, Peru, and Australia.
A trademarked designation for American-grown Pima cotton meeting strict quality standards set and enforced by the Supima Association. With a rigorous chain-of-custody authentication process from field to finished garment, Supima represents the top ~3% of U.S. cotton production, guaranteeing authenticated American Pima quality with no substitution or blending.
American Pima cotton grown under certified organic farming practices — no synthetic pesticides or fertilizers — and authenticated through Supima's traceability and quality standards. This variety combines the extra-long staple excellence of American Pima with the environmental commitment of organic agriculture, representing the highest standard across both dimensions simultaneously.
Grown along the Nile Delta, Egyptian cotton produces some of the world's finest extra-long staple fibers, often exceeding 1.5 inches. The unique humidity and climate of the Nile Valley yield threads of extraordinary fineness, producing fabric prized for its luminous sheen, silky hand feel, and remarkable longevity. Authenticity is certified by the Egyptian government.
Animal Fiber
Protein fibers harvested from sheep fleece, wool has clothed and insulated humans across thousands of years. Breed, micron count, and staple length determine the fiber quality, making Merino Wool the pinnacle of fine wool performance.
A protein fiber harvested from sheep fleece, sharing the same amino acid composition as human hair. Wool's naturally crimped structure traps air for outstanding warmth, while its outer scaly surface provides inherent moisture resistance. Quality depends on the wool's breed. Coarser wools suit outerwear and rugged applications, while finer grades serve garments worn directly against the skin.
Sourced from Merino sheep, this is the world's most technically advanced wool fiber. Merino's fine micron count — typically 15–24 µm — makes it soft enough for direct skin contact, eliminating the itch associated with standard wool. Its naturally springy, crimped structure stretches with movement and recovers fully, providing natural elasticity without any synthetic fiber blended in.
Animal Fiber
The only natural fiber produced as a continuous filament, silk has been one of the world's most coveted materials for over 5,000 years. Silk remains unmatched in luster, drape, and feel.
Produced by the Bombyx mori silkworm as it spins its cocoon, silk is the only natural fiber in continuous filament form. Each cocoon yields a single unbroken thread up to 900 meters long. Its triangular cross-section refracts light to produce silk's unmistakable luster, a quality no synthetic has replicated. A protein fiber like wool, silk is naturally hypoallergenic, temperature-regulating, and biodegradable.
Plant Fiber
Derived from the flax plant through a meticulous multi-step process, linen is one of the oldest known textiles and the strongest of all plant fibers. It only improves with age.
A bast fiber produced from the stalks of the flax plant through retting, scutching, and hackling. The result is approximately 30% stronger than cotton by weight, with a long staple that yields a naturally lustrous yarn. Linen starts firm and stiff, then softens distinctively with every wear and wash, developing character unique to each garment.
Linen produced from flax cultivated under certified organic standards — no synthetic pesticides or chemical fertilizers at any stage. Flax is inherently low-impact: it grows on rainwater alone, requires minimal fertilization, and enriches the soil it's planted in. Organic certification formalizes this already-sustainable baseline, ensuring a fully chemical-free chain from field to finished fabric.
Plant Fiber
One of the strongest and most sustainable plant fibers on earth, hemp has been cultivated for rope, textiles, and medicine for over 10,000 years. It only gets better from here.
A bast fiber from the Cannabis sativa plant, hemp is up to three times stronger than cotton by weight. Like linen, it starts firm and softens with wear. Hemp is naturally UV-resistant, mold-resistant, highly breathable, and absorbent. Its deep taproot aerates soil, suppresses weeds without herbicide, and returns nutrients to the earth, making it one of the most restorative crops in textile production.
Hemp grown under certified organic farming standards, ensuring no synthetic pesticides or fertilizers at any stage of production. Because hemp is naturally pest-resistant and soil-improving, organic certification formalizes what most hemp farmers already practice.
Hemp cultivated using regenerative agriculture practices that actively restore ecosystems — rebuilding topsoil, sequestering carbon, increasing biodiversity, and restoring watershed health. Where standard hemp avoids harm, regenerative hemp reverses it. Hemp's deep taproot draws CO₂ into the soil with exceptional efficiency, making this the highest-impact agricultural choice available in natural fiber textiles.
Animal Fiber
Rare, labor-intensive, and prized across cultures and centuries. These fibers embody the highest tier of natural textile quality, each with properties that no synthetic has come close to replicating.
Combed from the soft undercoat of Kashmir goats raised across the plateaus of Central Asia, cashmere is among the world's most coveted fibers. Its extraordinarily fine diameter — typically under 19 µm — produces an unmistakable softness no plant fiber can approach. Each goat yields only 150–200 grams of usable fiber per year, making genuine cashmere inherently scarce.
Harvested from alpacas raised primarily in the Peruvian Andes at high altitude, alpaca fiber comes in 22 naturally occurring colors — more than any other animal fiber. Its hollow-core shaft structure provides thermal insulation comparable to down while remaining lightweight. Alpaca contains no lanolin, resulting in a naturally hypoallergenic fiber and a good alternative for those with sensitivities to wool.
Produced by Angora goats — distinct from Angora rabbits, which produce Angora fiber. Commercially prized since the 19th century, Mohair's smooth, scale-free surface offers a luster that rivals silk among animal fibers. It is strong, elastic, and absorbs dye brilliantly, retaining vibrant color longer than almost any other natural fiber.
Harvested from Angora rabbits through shearing or gentle combing, Angora fiber sits among the softest and lightest natural materials available. Warmer than wool by weight, Angora's hollow-core structure provides exceptional insulation, while producing the distinctive soft halo that defines Angora knitwear. To improve durability, it is often blended with wool or silk, reducing the natural shedding of pure Angora.
