What Is Baby Cashmere? The Finest Expression of Luxury Wool

Among the world’s most exceptional fibres, baby cashmere sits in a category of its own. It is recognised not only for its remarkable softness, but for the delicacy of its touch and the sheer scarcity of its fibres. To understand baby cashmere is to understand a material shaped by nature, patience, and a commitment to craftsmanship.

Where Baby Cashmere Comes From

Baby cashmere is sourced exclusively from the downy undercoat of young cashmere goats raised in the remote plains of Inner Mongolia. These kids naturally shed their first fleece once a year. During that brief season, skilled herders gently comb the fibres by hand, never shearing or causing discomfort to the animals. The fibre yield from one baby goat is only a fraction of that from an adult, making the material exceptionally rare and highly prized.

What Makes Baby Cashmere Unique

Baby cashmere fibres are even finer and softer than premium adult cashmere. With an average diameter of around 13–14 microns, they create a level of smoothness that feels almost fluid to the touch. Their lightweight nature allows the knit to fall elegantly, making baby cashmere ideal for outerwear and garments that require both structure and grace.

Advantages of Baby Cashmere

• Extraordinary softness, noticeable even against sensitive skin

• Lightweight warmth, providing insulation without heaviness

• Finer fibres for a silk-like drape

• Uncommon rarity, as harvesting can only occur once in a goat’s lifetime

• Durability that improves with proper care

How Baby Cashmere Is Used

Baby cashmere is reserved for pieces that deserve a heightened level of luxury—double-faced coats, sculpted knitwear, seamless construction, and accessories that glide over the skin. It responds well to precision tailoring and refined stitching, allowing designers to shape garments that feel both weightless and architectural.
