Increasingly known as the “most luxurious fibre in the world”, Cervelt is hailed all over the globe for its incredible quality and wear. The extremely rare natural down fibre is collected from the down of New Zealand red deer.

Only 20g of the fibre can be collected from each red deer per year, making it the world's most sought-after natural fibre and its most expensive. With current world production being maintained at a limited amount each year, it justifies its description as the "diamond of luxury fibres”.

Cervelt is also the highest quality natural fibre in the world, boasting lightness, pill-resistance, and warmth via the action of millions of air chambers that form inside the natural creases of the fibre. It is a 13-micron fibre, making it finer than the finest cashmere. The diameter is consistent throughout its length, with a very low coefficient of variation meaning that all Cervelt fibre is consistently superfine.

The fibre is not straight, but has a wavy curl producing a yarn that is strong and resilient. The fibre retains its warmth even when the fabric or knitwear is very fine. These incredible natural properties have defined Cervelt as the most sought after new natural fibre in the world and a personal favourite of leading luxury brands internationally.
