The Duke
A hollow-fiber blend you won't find anywhere else.
Made in the United States, The Duke is crafted using seamless 3D knitting, forming a continuous garment without traditional seams for a more refined and durable construction.
Produced to order, each piece is created with precision to preserve the integrity of its materials. The knit is composed of 70% Merino Wool, 20% Koomal Fiber, and 10% Lyocell—a considered blend that delivers natural temperature regulation, breathability, and a smooth, cashmere-like hand feel with enhanced durability.
Fine ZQ Merino provides softness and performance, Koomal fiber contributes resilience while supporting ecological restoration, and lyocell adds fluidity and structure to the final fabric.
This composition is paired with a zero-waste 3D knitting process, reflecting a consistent philosophy: the material restores balance, and the method ensures nothing unnecessary is created. The seamless construction enhances both comfort and longevity, allowing the garment to maintain its form over time.
A more elevated essential defined by American craftsmanship, material precision, and disciplined construction.

Care
To preserve the shape and softness of your Èidean knit, we recommend professional cleaning. Store folded in a cool, dry place away from direct heat and light.
From Source to Spin
Each material in our yarns is chosen with care for its feel, performance, and impact. All of our pieces are built around Koomal, a sustainably sourced fiber from an invasive species in New Zealand. Using this fiber helps protect native forests and wildlife, giving purpose to what would otherwise be waste. Known for its warmth-to-weight ratio, breathability, and low pilling, Koomal offers lasting comfort across changing conditions.
Depending on the garment, Koomal is paired with complementary fibers selected for balance and longevity. ZQ Merino contributes natural softness, temperature regulation, and comfort against the skin, sourced under strict animal welfare and land stewardship standards. In other blends, cotton provides breathable strength while silk adds flexibility and a smooth, refined finish. Each combination is designed to feel composed, breathable, and dependable through regular wear.
Our yarns are crafted in New Zealand under strict environmental and ethical standards, where water and energy use are carefully managed and excess fiber is re-spun to minimize waste. The result is a consciously made material built for ease, integrity, and long-term wear.
