It Begins Before the Mill

Bison fiber is not inherently difficult. It is simply rarely handled with precision.

Most limitations in the final material can be traced back to how the fiber is removed, selected, and prepared before it ever reaches the mill.

Our process is built around controlling those variables—preserving the integrity of the fiber from the beginning.

A Different Standard

Professional Shearing

Most bison fiber is not professionally shorn.

We shear the hide in a way that preserves staple length, reduces contamination, and maintains consistency across the fiber.

This step defines everything that follows.

Dehairing to Specification

The separation of guard hair from undercoat defines the final material.

We approach this step with control and consistency, rather than treating it as a bulk process.

Not all fiber is usable.

We sort and select for length, cleanliness, and integrity before it ever reaches processing.

What is removed matters as much as what is kept.

Material Selection

Inside an industrial textile manufacturing facility, a large green textile machine is in operation, with fabric being woven or dyed. The machine has various controls and rollers, and there are some open containers and tools nearby, with sunlight coming through large windows in the background.

American Manufacturing

From scouring to spinning to weaving, the fiber is processed through American mills that understand natural materials.

Each stage is aligned to maintain the character and structure of the fiber.

An industrial machine is processing red fiber material, with scattered bits on the floor around it. A person is standing nearby, observing or operating the equipment in a workshop or factory setting.

The Result

The outcome is not just softness or warmth.

It is a material that is consistent, durable, and capable of being built into garments and textiles that last.
