How Does The Fiber Structure Affect Cervelt™ Textile Performance?
The unique curl of Cervelt™ fibers means they rarely lie straight, but instead twist and coil back on themselves. This affects nearly every characteristic of the resulting fabric:
- Incredible softness and suppleness
- Exceptional resistance to creasing and wrinkling
- Inherent elasticity and shape retention
- Exceptional thermal regulation and moisture management

Why Is Cervelt™ So Rare?
The fibre is 3000 times rarer than Cashmere, 200 times rarer than Gold and with supply initially being maintained at 1 tonne each year, it justifies its description as the "Diamond of Clothing"! Only 20 grams of this precious down are obtained from each red deer, making this fibre very rare, and rare it will remain as it is impossible to have a large-scale production.
What Is The Origin Of Cervelt™?
Cervelt™ is a completely natural down fiber combed from the underbelly of the native New Zealand Red Deer. This rare and precious fiber has been prized for centuries, but has only recently been commercially developed and produced by the experts at Douglas Creek Ltd.

What Are The Key Benefits Of Cervelt™?
- Ultra-lightweight - Cervelt™ is one of the lightest natural fibers, yet incredibly warm
- Breathable - The crimp structure allows excellent air permeability
- Hypoallergenic - Cervelt™ is naturally gentle on the skin Sustainable - Cervelt™ is a renewable natural resource


What Makes Cervelt™ So Exceptional?
The Cervelt™ fiber has an incredibly fine diameter, averaging just 13 microns - even finer than the most premium cashmere. But unlike cashmere, which has a more linear crimp, Cervelt™ fibers have a natural, springy curl. This coiled structure gives the yarn exceptional resilience and elasticity, which brings amazing thermal and wicking properties to the fabric.
