Alpaca

Alpaca is sold as warmer and softer than wool. Some of that holds up, some is marketing. Here is what the research and the trade’s own standards say.

At a glance

Origin: Animal fiber shorn from alpacas, South American camelids.

How processed: Natural, minimally processed: shorn, sorted by fineness, often dehaired to remove coarse fibers, then scoured and spun. No chemical conversion.12

What it is and how it’s made

Peru has about 87% of the world’s alpacas, more than 4.3 million animals, according to its agriculture ministry.3

Fleeces are graded by fineness. Under the Peruvian grades used by the alpaca trade association, “Baby Alpaca” means fiber up to 23 microns. It’s a grade, not the age of the animal.1

Coarse fibers are often removed by dehairing. In one study, about 91% of alpaca fleeces were above the prickle threshold and would need dehairing.2

How it wears

Softness and itchFibers coarser than about 30 µm cause prickle. Alpaca fleece is variable, and most fleeces carry enough coarse fiber to prickle unless they are dehaired.2
WarmthMany alpaca fibers are medullated (partly hollow), which helps the animal retain heat and makes garments light for their bulk. We found no garment trial showing alpaca is warmer than wool.4
DurabilityStrongly and continuously medullated fibers are coarser, can prickle, dye unevenly and are less resistant in textile processing, so mills try to remove them.5
MoistureWe found no independent data on alpaca’s moisture uptake in garments. Published regain figures we use cover wool, cotton and polyester only.6
OdorOdor studies rank wool well, but they didn’t test alpaca, so we don’t extend the claim.7
BreathabilityFabric studies in heat and cold point to construction over fiber; we found none on alpaca specifically.8
WrinklingWe found no crease data for alpaca; the alpaca garments we list are knitwear rather than woven shirting.9
CareBrands usually advise hand washing alpaca knitwear.9

Environmental notes

  • Alpaca herding is the main livestock activity above 4,000 m in Peru, supporting about 82,000 producers; fiber is about half of small breeders’ income.3
  • Footprint scorecards have ranked alpaca badly: PETA cites the Higg MSI rating alpaca second-worst after silk. Regulators have said Higg MSI can’t support fiber comparisons, and the coalition behind it paused consumer use. We found no independent life cycle study of alpaca fiber.101112

Counterpoints and caveats

  • Welfare: a 2020 PETA undercover investigation at Mallkini, a large Peruvian alpaca farm owned by the Michell Group, filmed rough shearing; Gap and H&M cut ties with the supplier.10
  • Only about 7% of global alpaca fiber (430 tonnes) was certified to the Responsible Alpaca Standard in 2023, all from Peru.13
  • It can itch: most fleeces need dehairing to get below the prickle threshold.2
  • Grading terms come from the alpaca trade association, not an independent body.1

Buying tips

  • “100% alpaca” or alpaca with wool is all natural. “Alpaca blend” says nothing about the share; read the percentages.
  • “Baby alpaca” means fiber up to 23 microns under the trade grades; it’s the softest common grade, not fiber from young animals.1
  • If welfare matters to you, look for the Responsible Alpaca Standard (RAS) on the label.13
  • If you find wool prickly, choose finer grades; prickle comes from fibers over about 30 µm.2

Common garments

  • Sweaters and cardigans
  • Beanies and scarves
  • Ponchos and unlined outer layers
  • Socks (usually blended)

Short answers

Is alpaca itchy?

It can be. Fibers coarser than about 30 µm cause prickle, and most alpaca fleeces need dehairing to remove them.21

Counterpoint: Finer grades such as baby alpaca are much less likely to prickle.

Does “baby alpaca” come from baby alpacas?

No. It’s a fineness grade: fiber up to 23 microns under the Peruvian grades used by the trade association.1

Counterpoint: The grading comes from an industry body.

Is alpaca ethical?

It depends on the farm. A 2020 investigation filmed rough shearing at a large Peruvian farm; the Responsible Alpaca Standard covered about 7% of global fiber in 2023.1013

Counterpoint: The investigation was by PETA, which opposes all animal fibers; the standard is owned by an industry-backed non-profit.
