China produces approximately 70% of the world's raw cashmere. Mongolia accounts for roughly 20%. The rest comes from smaller producers in Central and South Asia. But within that enormous Chinese production volume, the quality varies as dramatically as the geography.
The finest cashmere fibre — consistently grading under 15.5 microns — comes from one specific region: the Alxa (Alashan) desert area in western Inner Mongolia. Understanding why Inner Mongolia produces the world's finest cashmere fibre requires understanding the relationship between climate, biology, and fibre development.
The Alxa region sits at the intersection of three deserts: the Tengger, Badain Jaran, and Ulan Buh. It is one of the most extreme inhabited environments in Asia.
Winter temperatures regularly drop to -30°C and below. The air is bone-dry — humidity levels are among the lowest of any inhabited region. There is minimal vegetation, and what exists is sparse and coarse.
These conditions create a survival problem for the cashmere goats that live here. Their solution is biological: they grow an extraordinarily dense, fine undercoat beneath their coarser outer guard hair. This undercoat traps body heat by creating millions of tiny insulating air pockets close to the skin.
The colder and drier the environment, the finer and denser the undercoat needs to be. This is why Alxa cashmere consistently measures 14 to 15.5 microns — the goats' survival depends on producing fibre at that fineness.
Cashmere goats raised in milder climates — lower altitude, warmer winters, higher humidity — still produce undercoat fibre. But it's measurably coarser, typically grading at 16 to 19+ microns.
The reason is straightforward: milder conditions don't demand the same density of insulation. The goats' undercoat develops adequately for their environment, but "adequate" in a mild climate is not the same specification as "adequate" at -30°C in a desert.
This is not a reflection of goat breed alone — though breed matters. It's primarily an environmental effect. The same breed of goat moved from the Alxa desert to a temperate grassland would, over generations, produce coarser undercoat because the selection pressure for ultra-fine fibre would be reduced.
In the Alxa region, cashmere is traditionally collected by hand-combing during the spring moulting season. As temperatures rise, the goats' undercoat naturally loosens and separates from the outer guard hair. Herders use wide-toothed combs to gently pull the loosened undercoat free.
This process has several quality advantages over machine shearing:
Cleaner fibre separation. Hand-combing selectively removes the fine undercoat while leaving most of the coarse guard hair attached. This produces a higher-purity raw fibre that requires less mechanical dehairing.
Less fibre damage. Combing follows the natural direction of the fibre and removes only what's already loose. Machine shearing cuts all fibre — coarse and fine — at once, and the cutting action can damage fine fibre ends.
Natural timing. Hand-combing happens when the undercoat is naturally ready to shed. The fibre is at its full staple length and easiest to separate cleanly.
The tradeoff is speed. Hand-combing is slow and labour-intensive. But for the finest cashmere grades, the quality difference justifies the time investment.
Several distinct cashmere goat strains inhabit the Alxa region, each adapted to their specific micro-environment. The most recognised include:
Alasan goats — named after the Alxa League administrative region. Known for producing some of the finest cashmere fibre available, with consistent sub-15-micron grading.
Erlangshan goats — found in the mountain areas within the Alxa region. Their fibre is prized for both fineness and staple length.
These are not factory-bred animals. They live in semi-wild herding conditions on vast desert steppe, grazing on the sparse vegetation available. Their diet, movement patterns, and exposure to the elements all contribute to the fibre they produce.
A single Alxa cashmere goat produces approximately 100 to 200 grams of usable undercoat fibre per year. After dehairing (removing the remaining guard hair), the usable yield can be even less.
For context: a single cashmere sweater requires the annual yield of roughly three to five goats. The fibre production cannot be artificially accelerated. You cannot greenhouse-farm cashmere goats in controlled environments and produce the same quality fibre — the extreme natural conditions are what make the fibre exceptional.
This natural scarcity is the primary driver of cashmere pricing. It's not artificial scarcity created by brands — it's biological scarcity imposed by the goats' physiology and the harsh environment that shapes it.
The relationship between cashmere goats and the Inner Mongolian grassland is ecologically complex. Overgrazing is a genuine concern — cashmere goats are harder on pasture than sheep because they pull grass up by the roots rather than clipping it.
Responsible herding practices in the Alxa region include:
These practices matter not just for environmental reasons but for fibre quality: overgrazed land produces sparser, lower-quality vegetation, which in turn produces less healthy goats with coarser fibre. Sustainable herding and premium fibre quality are directly linked.
Any brand can claim Inner Mongolian origin. Here's what credible sourcing looks like:
Inner Mongolia produces the world's finest cashmere because of a simple chain: extreme climate forces exceptional fibre development, hand-combing preserves that quality, and careful sorting produces Grade A fibre that milder regions cannot consistently replicate. This isn't marketing mythology — it's measurable biology. Vionisxy exists specifically because of this region. Our cashmere comes from the Alxa desert, measures 14.5 microns, and is verified by SGS testing, because when the origin story is real, it should come with evidence.
