How to Wash Qiviut
Qiviut is muskox underdown — 15–18 microns, lanolin-free, and 6–8× warmer than wool by weight. Scale protrusion is lower than merino, giving a wider safety margin before felting, but machine washing is still destructive on a garment worth hundreds of dollars. Cold hand wash, enzyme-free detergent, lay flat.
The Chemistry
Qiviut is the soft inner down layer of the muskox (Ovibos moschatus), a large bovid native to the Arctic tundra of Canada, Alaska, and Greenland. Muskoxen are not sheared — the underdown is combed out or collected from shedding animals during the natural spring moult. This means qiviut production is inherently limited by the animal's biological cycle and cannot be scaled through intensive farming practices at the rate possible with sheep wool or even cashmere goats. These supply constraints make qiviut among the most expensive commercial natural fibres available — fine qiviut garments routinely cost $300–$2000+, placing correct washing technique in a different category of importance from most other fibres. The fibre diameter of qiviut averages 15–18 microns, placing it in the same range as the finest Grade A cashmere (typically 14–16 microns) and substantially finer than alpaca (16–30 microns depending on breed, with baby alpaca around 20–22 microns) or fine merino (18.5 microns is the standard itch-free threshold for merino). At these diameters, individual fibres are below the threshold at which the human skin can detect individual contacts — both qiviut and the finest cashmere are genuinely itch-free for essentially all people. The scale structure of qiviut is present but has lower scale protrusion than merino of comparable diameter. The scale protrusion — the height of the scale edge above the fibre body — is the primary driver of felting: higher protrusion means the scales interlock more efficiently under heat and agitation. Qiviut scales are shallower and smoother than merino, which reduces the rate at which fibres migrate and entangle under mechanical stress. This gives qiviut a wider safety margin before felting than merino of equivalent micron count — but qiviut is not felt-proof. Prolonged machine agitation, high temperatures, and especially the combination of both will felt qiviut. The safety margin means accidental warm hand washing is unlikely to cause immediate disaster; machine washing on a standard cycle is not a risk worth taking with a $500 garment. Qiviut contains no lanolin. Like alpaca and cashmere, it comes from an animal whose fibre does not carry the sebaceous wax that sheep produce. This means qiviut is not irritating to most people with lanolin sensitivity, and the marketing claim of hypoallergenic is more defensible for qiviut and cashmere than it is for sheep's wool. However, a small minority of people react to the keratin protein itself rather than the wax, in which case qiviut is not hypoallergenic for them either. The warmth-to-weight ratio of qiviut is exceptionally high. Published figures from textile research institutions suggest qiviut is approximately 6–8 times warmer than sheep's wool of the same weight. This arises from a combination of factors: the fine diameter means a large number of fibres per unit weight, creating a dense, still-air-trapping structure; the fibre also has some degree of medullation (hollow or semi-hollow core similar to alpaca), contributing to the trapped-air insulation effect; and the natural scaling of the fibre surface creates micro-pockets between fibres that further inhibit convective heat loss. The practical consequence is that a thin qiviut garment provides warmth comparable to a much heavier merino garment. The comparison to cashmere is the most relevant benchmark for purchasing and care decisions. Both are fine-diameter protein fibres around 15–18 microns; both are lanolin-free; both come from combing rather than mechanical shearing; both require enzyme-free detergent and cold hand washing. The primary differences: qiviut fibres are longer on average than cashmere, which makes them more resistant to pilling (pilling in cashmere occurs because short fibres migrate to the surface and roll together under friction — longer fibres remain anchored in the yarn structure more effectively); qiviut is warmer per unit weight; and qiviut is significantly more expensive, with limited availability. Enzyme detergent is as destructive to qiviut as to any protein fibre — protease enzymes cannot distinguish between food protein stains and qiviut keratin. The progressive fibre thinning caused by enzyme detergent would be particularly costly given qiviut garment prices. Use only pH-neutral, enzyme-free detergent labelled for wool, cashmere, or silk.
Step-by-step
- 1
Cold hand wash only — qiviut can felt under machine agitation despite lower scale protrusion than merino
Qiviut scales are shallower than merino of the same diameter, giving a wider safety margin before felting — but the risk is real under mechanical agitation. At the price of a qiviut garment, no machine wash cycle is an acceptable risk. Cold water (below 20°C) and hand washing only. If you have previously hand washed qiviut at slightly above cold (lukewarm) and it survived, note that each wash adds cumulative stress to the scale structure — cold is always safer than even slightly warm.
- 2
Use enzyme-free, pH-neutral detergent — protease digests qiviut fibre protein exactly as it digests stains
Qiviut is keratin — the same protein family as all animal fibres. Enzyme (biological) detergents contain protease that breaks down protein chains. They cannot distinguish between a food protein stain and qiviut keratin. Repeated washing with enzyme detergent progressively thins fibres, eventually causing surface balling and weakening of the knit structure. Use a product specifically formulated for wool, cashmere, or silk — these are enzyme-free and pH-neutral. Baby shampoo is an acceptable alternative. Never use regular laundry detergent.
- 3
Dissolve detergent fully before submerging — use minimal detergent (a few drops is enough)
Fill a basin with cold water and dissolve the detergent thoroughly before adding the garment. Given qiviut's cost and fineness, use significantly less detergent than you would for wool — a few drops of a wool wash concentrate is sufficient for a single garment. Excess detergent is harder to rinse fully and leaves residue that dulls the fibre surface over time. Submerge the garment gently without agitation.
- 4
Soak 5 minutes with no agitation — never rub, squeeze, or swirl
Qiviut cleans well with minimal effort — the combination of cold water and a small amount of detergent dissolves body oils and odour through soaking alone. Do not rub localised areas, squeeze the garment, or swirl it in circles — all of these create the relative fibre movement that drives scale interlocking. If specific areas need attention, apply a small amount of undiluted detergent to those areas before the soak and let the product work rather than applying mechanical force.
- 5
Rinse twice in cold water of the same temperature — temperature change causes uncontrolled fibre response
Sudden temperature changes between wash and rinse water — even from cold to slightly less cold — can cause unpredictable scale movement. Use the same cold temperature throughout. Run two separate rinse cycles in clean cold water, each for 2–3 minutes of passive soaking (no agitation). Qiviut is fully rinsed when the water runs clear and you detect no detergent character in the rinse water. Detergent residue is difficult to feel on a fibre this fine — err toward a third rinse if in doubt.
- 6
Press out water between clean towels — never wring, never twist
Lift the garment from the rinse water supporting its full weight with both hands from underneath. Lay it flat on a clean dry towel. Fold the towel over the garment and press firmly along the entire surface without any twisting or rolling motion. The goal is mechanical water extraction through towel absorption. Replace with a fresh dry towel if the first becomes saturated. Wringing or twisting is the single most dangerous action for a wet qiviut garment — the mechanical force directly initiates scale interlocking.
- 7
Lay flat on a clean dry surface and reshape while pliable — never hang qiviut
Lay the damp garment flat on a clean fresh towel or mesh drying rack. Gently reshape to the original dimensions while the fibre is pliable from being wet — if measurements matter, note them dry before washing. Never hang qiviut to dry — the weight of the wet garment will elongate the knit structure at the stress points (especially shoulders and underarms) permanently. The fine, lightweight fibre of qiviut holds proportionally more water than its weight suggests, and the wet weight is concentrated during hanging. Air dry flat at room temperature away from direct heat sources and direct sunlight (UV degrades protein fibres over time).

Frequently asked questions
What is qiviut and why is it so expensive?
Qiviut is the inner underdown layer of the muskox, an Arctic bovid native to Canada, Alaska, and Greenland. Muskoxen are not sheared — the down is combed out during the natural spring moult or collected from shed fibre. This means production cannot be scaled the way wool or cashmere production can: each animal produces roughly 1–2 kg of raw fibre per year, and the animals cannot be pushed to produce more. Combined with limited geographic range and small breeding populations, supply is fundamentally constrained. The fibre averages 15–18 microns (as fine as the best cashmere), is 6–8× warmer than wool by weight, and is genuinely soft against skin. These properties combined with very limited supply produce retail prices of $300–$2000+ per garment.
Is qiviut hypoallergenic?
Qiviut is lanolin-free — it contains no natural wax, which is the primary irritant for most people who react to wool. For the majority of wool-sensitive individuals, qiviut is genuinely non-irritating. The fineness of the fibre (15–18 microns, below the itch threshold for human skin contact) further reduces the sensation of prickling that coarser fibres cause. However, a small number of people react to keratin protein itself rather than to lanolin, and for them qiviut is not hypoallergenic. The combination of fine diameter and no lanolin makes qiviut one of the least allergenic natural fibres available.
How does qiviut compare to cashmere?
Both qiviut and cashmere are fine, lanolin-free protein fibres in the 14–18 micron range requiring identical care: enzyme-free detergent, cold hand wash, lay flat to dry. The key differences: qiviut fibres are longer on average than cashmere, which reduces pilling (pilling occurs when short fibres migrate to the surface and roll into balls under friction — longer fibres stay anchored in the yarn structure). Qiviut is approximately 6–8× warmer than wool by weight, compared to cashmere's approximately 3× advantage over wool. Qiviut is significantly more expensive and less widely available. The softest Grade A cashmere (sub-14 micron) may feel marginally softer than average qiviut, but the warmth and pilling resistance of qiviut give it different practical advantages.
Does qiviut shrink or felt?
Qiviut can felt — it has a scale structure, and scale interlocking under heat and mechanical agitation causes irreversible felting in all protein fibres. The scales on qiviut fibres are shallower and less prominent than in merino of the same diameter, which gives qiviut a wider safety margin before felting begins — it requires more agitation than merino to initiate scale interlocking. But machine washing on a standard cycle is more than sufficient to felt qiviut, and any machine wash cycle is an unacceptable risk on a garment worth hundreds of dollars. Cold hand wash with no agitation is the only appropriate method.
