Polyester vs. Vicuña
How the world's rarest wool exposes fashion's race to the bottom
In November 2025, on the Altiplano of northern Chile, a community gathered at 13,000 feet above sea level before a volcano.
Before the work began, an elder named Don Maximiliano Huayllas led a Pawa — a ceremony of gratitude to the land, an act of reciprocity before taking from it.
Then the chaku started as a coordinated human effort moving across the high plains, herding vicuñas with nets, ropes and ribbons, with centuries of knowledge encoded in the choreography.
Fifty-four vicuñas were captured and each animal was assessed by a veterinarian. Pregnant females and their young were released immediately, along with any animals showing signs of illness. Only those who meet the health and fiber-length criteria were left to be shorn. The yield from the entire event?
Just over 15 pounds of fiber.
This was the second phase of a UNESCO-led initiative funded by Spain’s Autonomous Organism of National Parks, designed to revive Aymara community -based vicuña management in Chile’s Lauca Biosphere Reserve. It’s a region where out-migration has caused traditional practices to disappear over generations.
More than 40 participants were trained across veterinary protocols, population monitoring, animal welfare, and ancestral ceremony. Two days of coordinated effort by an entire community, guided by both scientific methodology and pre-Incan tradition for just fifteen pounds of fiber.
Loro Piana’s vicuña crewneck retails at $9,000. A jacket, $25,000. A Salzburg cape, $31,750. Brioni’s bespoke vicuña commissions start at €12,000. These houses call vicuña “the fiber of the gods.” What they mean, economically, is that the entire yield of that UNESCO chaku — two days, 54 animals, a community, a ceremony, a volcano — would wholesale into roughly five to seven luxury sweaters.
What vicuña actually is, and why it can’t be scaled
The vicuña is a wild South American camelid that produces the finest natural fiber on earth measuring between 12 and 14 microns, which is finer than the finest cashmere and resilient enough to withstand over 20,000 bends before showing wear.
Each animal yields four to six pounds of fiber per year, combed or gathered, never shorn to the skin. It cannot be domesticated at commercial scale or farmed without losing the qualities that make it valuable. The geography and altitude it requires in the Altiplano, Andes, and other high cold environments cannot be relocated in a production facility.
By the 1960s, it was nearly gone. Centuries of hunting and poaching had reduced the global population to approximately 6,000 animals. When a 1969 CITES listing banned trade in vicuña fiber entirely, the population slowly recovered under protection. An international treaty eventually reinstated a legal market under one non-negotiable condition that income from vicuña must benefit Indigenous Andean communities.
As a result, Peru generated $3 million from exporting 7 tons of vicuña fiber the same year it generated $300 million from alpaca in 2019. Vicuña fabric trading at $1,800 to $3,000 per yard is a controlled trickle, and the price reflects that reality honestly.
Where the luxury houses enter and what they do with the story
Loro Piana entered the legal vicuña market in 1994, when the Lucanas community in Peru became the first to shear vicuñas under the new legal regime. The Italian house was acquired by LVMH for €2 billion in 2013 and has since been Lucanas’ exclusive buyer for thirty years. Brioni, the Roman tailoring house now owned by Kering, draws from the same network of protected Andean suppliers for bespoke commissions. Both brands funded the conservation infrastructure that has recovered the vicuña population to approximately 350,000 animals to date.
The conservation work deserves credit, but a Bloomberg Businessweek investigation published in March 2024 found something the brand narrative doesn’t surface. The Lucanas community of 2,700 people, receives approximately $280 for an amount of fiber that Loro Piana sells as a $9,000 sweater. The herders who perform the chaku are not paid wages either. Andrea Barrientos, a 75-year-old subsistence farmer, joins her village once a year to drive vicuñas across the high plain and shear them without compensation. Thirty years of supplying the world’s finest wool has done, by the investigation’s account, almost nothing for the village.
Loro Piana is not lying, so this isn’t greenwashing in the traditional sense of fabricated certifications or semi-synthetics marketed as natural. The fiber and conservation is real. The question is whether the story of Indigenous stewardship, ecological restoration, and ancestral practice is embedded in the product and extracted as brand equity.
The communities supply the story alongside the fiber while the margin accrues in Milan and Rome. LVMH and Kering as two of the largest luxury conglomerates on earth are the vessels through which the margin flows.
Bibiana Vilá, a scientist from the VICAM research team in Argentina who participated in the UNESCO Lauca initiative, put it plainly: “For communities to benefit fully, reducing reliance on large intermediaries and promoting direct access to green market niches that value both quality and sustainability is essential.” She is describing, precisely, what the current structure prevents.
What an honest model looks like
The UNESCO Lauca initiative is a conservation project and a participatory model where horizontal dialogue between scientists, Aymara knowledge holders, and public authorities is designed to be replicated across the Andean region. The goal is community ownership of the value chain and that model has a working proof of concept 6,000 miles north, in Anchorage, Alaska.
Oomingmak, the Musk Ox Producers’ Co-Operative, has operated since 1969. It is owned by approximately 250 Native Alaskan women from remote coastal villages who knit each item by hand. The fiber is qiviut — the downy underwool of the Arctic musk ox, shed naturally each spring, gathered from tundra brush or combed during seasonal collection. It measures 15 to 20 microns, eight times warmer than wool by weight, and it only exists in the quantities the tundra produces.
Each member pays a $2 annual membership fee, receives qiviut yarn and a copyrighted cooperative pattern. She knits at her own pace, in her own village, in patterns that belong to her community in the form of harpoons, stars, and seal hunt stories encoded in lace. When she ships her finished items to Anchorage, she is paid within one day. At year’s end, she receives a profit-sharing dividend.
The knitters are the shareholders but an acquisition of Oomingmak is structurally impossible because the community is the enterprise, and has been for over fifty years. The price of a qiviut scarf is high because the cost is honest and the margin stays where the hands are.
The system, not the material
The problem was never that the textile industry didn’t know externalizing cost was destructive. The problem is that the accounting system it operates inside makes externalizing cost the rational choice every time, at scale, for decades.
Recycled polyester is the most clarifying data point here. When the industry came under pressure to address the environmental cost of virgin poly, it produced another product as the solution — recycled PET, bottle-to-fabric pipelines, sustainability certifications — that answered the PR pressure without touching the underlying problem.
Recycled polyester produces 55% more microplastic pollution during washing than virgin polyester, and the particles are nearly 20% smaller and more penetrating. The solution made the problem measurably worse while allowing the system to keep running and the marketing to say otherwise. That is what happens when you ask a profit-extraction model to fix a problem that profit extraction created.
The deeper issue is one the fiber industry shares with every extractive industry on earth is that extraction economies are premised on the planet being infinite, and it isn’t. The Aymara communities practicing the chaku have understood this for centuries.
The vicuña cannot be farmed at scale any more than the musk ox can be industrialized. And these aren’t supply chain constraints to be engineered around.
They are the system working correctly by pricing scarcity honestly and refusing to let the cost be moved somewhere invisible.
