The Billy
A hollow-fiber blend you won't find anywhere else.
Made in the United States, The Billy is produced using seamless 3D knitting, forming a continuous garment without traditional seams.
Knitted at a heavier weight and made to order, it preserves the qualities of its cotton, silk, and Koomal fiber blend—offering warmth, structure, and a soft, cashmere-like hand feel.
The zero-waste process reflects the same intention behind the material, ensuring alignment between sourcing and construction. Seamless design enhances durability while maintaining a refined silhouette.
A measured balance of weight, softness, and American craftsmanship.
Please allow 7–10 business days for production prior to shipping.

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.
