To tell good quality cashmere, squeeze it: it should feel dense and spring back. Rub a small patch: it shouldn't pill or shed right away. Avoid a slippery, too-soft hand. Check that ribbing recovers and seams are linked, not sewn. Online, read the fiber percentage, ply, gauge and yarn origin.
A label that says "100% cashmere" tells you the fiber. It doesn't tell you the grade. Two sweaters with identical labels can feel the same in the store and look completely different after ten wears. The checks below come from textile experts, Wirecutter's hands-on testing of nearly 70 sweaters, US labeling law, plus the spec details we publish on our own cashmere listings.
What Makes Cashmere Good or Bad?
Cashmere quality comes down to two fiber traits: length and fineness. The Cashmere and Camel Hair Manufacturers Institute, quoted by Condé Nast Traveler, puts it plainly: "The most important factor in the quality of cashmere is the length and fineness of the fibers." The same statement adds that garments made with long, thin fibers "pill less and maintain their shape better than cheaper, lower quality cashmere and will get better with each wash."
Short fibers have more loose ends. Those ends work their way to the surface, tangle, and form pills. Wirecutter reports that the least expensive sweaters tend to use yarn spun from "coarser, shorter, and broken fibers."
In the US, "cashmere" also has a legal floor. Under the FTC's rules for wool product labels (16 CFR 300.19), a fiber can be labeled cashmere only if:
- it is the fine, dehaired undercoat of the cashmere goat,
- its average diameter is no more than 19 microns, and
- no more than 3% of the cashmere fibers by weight average over 30 microns.
That rule defines what cashmere is. It doesn't rank it, which is why the hands-on checks still matter.
Scarcity explains the price. Wirecutter notes that cashmere goats live mainly in the harsh, high-altitude regions of Mongolia, China and Afghanistan. It can take around four goats to produce enough fiber for one sweater.
5 Hands-On Tests for Cashmere Quality
Squeeze it: good cashmere feels dense and springy
Cashmere designer Carolyn Yim told Condé Nast Traveler that cashmere "should always feel creamy, heavy, dense, hefty" and "almost springy when you squeeze it." Density reflects knitting tension. The same article explains that cheaper products often use a looser tension because it takes less yarn. A loose knit can feel softer in the store but is "more likely to pill and warp later."
Try this: Hold the knit up to a window. A fine-gauge knit will let some light through, and that's normal. What you're checking is evenness: thin patches, uneven stitches or a see-through body on a supposedly warm sweater are warning signs.
Do the rub test
Rub a finger firmly over the forearm of the sleeve for a few seconds. Wirecutter's testers did exactly this and treated any immediate pilling, lifting or shedding as a bad sign. For scale, Wirecutter's most pill-resistant pick, a compact 12-gauge, 2-ply knit, needed more than 100 rubs on one spot before a pill formed. A denser 7-gauge, 2-ply polo took about 50 firm rubs.
A little early shedding can happen with good cashmere. A knit that pills under your fingertip in the fitting room is telling you how it will look in March.
Check the surface, and be wary of "too soft"
Look across the surface in good light. Wirecutter's testers read heavy fuzz as a sign of shorter fibers, and they called a sweater with "almost no surface fluff" a good indicator of longevity.
Softness can mislead. Wirecutter warns that cashmere that feels "supernaturally soft or slippery has likely been over-washed or chemically softened to mask the feel of rougher, lower-quality fibers." Good cashmere feels soft and substantial, not slick. Some well-made sweaters aren't cloud-soft on day one. Wirecutter found that one of its higher-quality picks softened with wear and careful care.
Stretch the ribbing
Gently pull a cuff or the hem, then let go. It should spring back without staying stretched or wavy. Wirecutter tugged sleeves and ribbing on every sweater, looking for knits that didn't warp or lose their shape.
Turn it inside out: seams, cuffs and neckline
Wirecutter prefers fully fashioned knits, where each piece is shaped during knitting and then linked together, rather than cut and sewn. You can usually spot it by small raised marks along the shoulders and collar where the stitches were decreased. The result is flatter, more flexible seams and a better fit.
Condé Nast Traveler adds two quick checks: the cuffs and bottom rib should lie flat without puckering, and a crew neck should be a perfect semicircle, not a U-shape.
Buying Cashmere Online: How to Read the Product Page
You can't squeeze a sweater through a screen, so the product description has to do the work. These are the details worth looking for, and what each one tells you.
|
What the listing says
|
What it means
|
What to look for
|
|
Fiber content, e.g. "100% Cashmere" or "65% Cashmere 35% Merino Wool"
|
US labels must state each fiber's percentage, and FTC rules bar a label from implying cashmere that isn't in the fiber content. A clearly labeled blend is not fake cashmere.
|
A clear percentage. Be cautious of "cashmere feel" or "cashmere touch" with no cashmere listed.
|
|
Ply, e.g. "2-ply," "three-ply"
|
How many strands are twisted into one yarn. Wirecutter: higher ply means more warmth and durability.
|
2-ply or more for a sweater you'll wear often. Single-ply suits featherweight layers.
|
|
Gauge, e.g. "12-gauge," "fine-gauge"
|
Stitches per inch. Higher is finer and lighter; lower is chunkier.
|
The weight you want. Gauge describes the style of knit, not its grade.
|
|
Weight in grams
|
How much yarn went into the garment.
|
Useful for comparing similar styles. More grams generally means more yarn and a warmer, heavier knit.
|
|
Yarn origin, e.g. "Italian-spun"
|
Where the yarn was spun. Condé Nast Traveler notes top-quality cashmere generally comes from mill towns such as Biella, Italy and Hawick, Scotland.
|
A named spinning location is a better sign than none.
|
|
Construction, e.g. "fully fashioned"
|
Pieces shaped and linked, not cut and sewn.
|
Fully fashioned or linked seams.
|
|
Pilling grade, e.g. "Grade-4 anti-pilling"
|
Lab pilling tests (ISO 12945) grade fabric from 5 (no change) to 1 (severe pilling); 4 means partially formed pills.
|
Grade 4 or higher. Treat it as a lab result, not a promise of zero pills.
|
|
Certification, e.g. "GCS-certified"
|
Wirecutter describes Good Cashmere Standard certification as independent standards for animal welfare, land management and labor conditions.
|
A named standard, if sourcing matters to you.
|
Here's how those details read on our own listings:
- Construction: Our Ultrasoft Brushed Cashmere Marled V-Neck Sweater is described as fully fashioned and knit from a double-ply, four-strand marl yarn.
- Yarn origin and ply: The Italian-Spun 100% Cashmere Cable Knit Double-Zip Cardigan lists Italian-spun yarn and a three-ply knit.
- An honest blend: The Chunky Cashmere-Merino Cable Knit Hooded Cardigan states 65% cashmere and 35% merino wool in a 3-ply yarn, so you know exactly what you're paying for.
Across our cashmere collection, stated ply counts run from single-ply featherweights to seven-ply statement knits. If a listing you're considering doesn't show a detail you care about, ask before you buy. Italian Atelier Cashmere Collection>>
Ply and Gauge, Explained
Ply is the number of strands twisted into one yarn. Gauge is the number of stitches per inch. Neither number is "better" by itself. They describe weight and texture, and both work together with fiber quality.

Feel
|
Example from Wirecutter's testing
|
|
12-gauge and finer
|
Smooth, light, easy under a blazer
|
A 12-gauge, 2-ply polo that resisted pilling for 100+ rubs; a 12-gauge single-ply knit that felt "floaty"
|
|
7-gauge
|
Cushy, mid-weight, more texture
|
A 7-gauge, 2-ply polo that took about 50 firm rubs to pill
|
|
3- to 5-gauge
|
Chunky, warm, coat-weather
|
A 3-gauge, 5-ply sweater testers called "really thick and cozy"
|
Chunkier knits have larger loops, which Wirecutter notes can snag more easily, so they need a gentler hand when de-pilling. For a polished layer, start with a fine gauge. Lightweight Cashmere>>
Brushed Cashmere: The Trade-Off
Brushed cashmere is brushed on purpose to raise a soft halo. COS's fall 2026 campaign described "the soft halo of brushed cashmere," and it's one of the coziest textures you can wear. Go in with clear expectations, though. Wirecutter's rule of thumb is that more surface fluff typically translates to more pilling.
With brushed styles, the fluff itself isn't a warning sign, so look past it. Check for a dense knit underneath, ribbing that springs back, and a stated ply or pilling grade. Our 3-Ply Brushed Cashmere Free-Collar Pullover, for example, lists 100% cashmere, a 3-ply yarn and Grade-4 anti-pilling.
Does Price Equal Quality?
Up to a point. Imran Islam, an associate professor of textile development and marketing at the Fashion Institute of Technology, told Wirecutter: "Once a product reaches a high-quality baseline, further price increases are often tied to brand positioning, exclusivity, or design." You don't need a four-figure sweater to get excellent cashmere.
The bottom of the market is riskier. Textile historian Celine Khawam, who teaches at Parsons, told Wirecutter that a 100% cashmere sweater at bargain prices "almost always involves compromises in fiber length, fineness, construction, or ethical sourcing." Islam also warned that "many fabrics labeled as '100% cashmere' may in fact contain cheaper animal fibers." Even Wirecutter's favorite budget pick came with a caveat: it pills more quickly than most.
The practical takeaway: in the mid-to-premium range, judge the knit and the spec line, not the price tag alone.
Red Flags Checklist
- Pills, lifts or sheds the moment you rub it
- Feels slippery or "too soft" in a way that seems coated
- Heavy surface fuzz on a sweater that isn't sold as brushed
- Loose, uneven knit or thin patches when held to the light
- Ribbing that stays stretched after a gentle pull
- Puckered cuffs or a U-shaped crew neck
- A listing with no fiber percentages, or "cashmere feel" with no cashmere in the content
- A 100% cashmere price that seems too good to be true
How to Care for Cashmere So It Lasts
"All cashmere needs to be treated with care — and even the best stuff will pill," Wirecutter says. Care is what keeps a good sweater looking good for years. Wirecutter's care guide recommends:
- Hand-wash in lukewarm water with a gentle detergent or baby shampoo diluted in the water. Soak about 15 minutes, swirling occasionally. Never use the dryer.
- Dry flat. Roll the sweater in a towel to press out water, then lay it flat in shape, with no bunched sleeves or rolled hems.
- Fold, don't hang. Hanging can stretch the fabric and loosen the fibers.
- De-pill only when needed. Use a cashmere comb in gentle strokes. Combing too often thins the knit.
- Store clean and sealed in the off-season. Moths love natural fibers.

Where to Start This Fall
Once you know what quality looks like, build slowly. One fine-gauge crewneck in a neutral covers office days and layers under a coat. One cardigan handles weekends. If you want color, PORTER's fall/winter 2026 trend report points to bottle green, ochre, scarlet and purple, and Who What Wear highlights royal purple and buttercream. Our fall 2026 guide for women over 35 has outfit formulas for working these shades in.
FAQ
How can you tell if cashmere is good quality?
Squeeze it: good cashmere feels dense and springs back. Rub a small patch; instant pills or shedding are a warning. Avoid a slippery, too-soft hand, which can signal chemical softening. Check that ribbing recovers and seams are linked. Online, look for fiber percentages, ply, gauge and yarn origin in the description.
Is 2-ply cashmere better than 1-ply?
For everyday sweaters, usually yes. Ply is the number of strands twisted into the yarn, and Wirecutter notes that a higher ply generally means more warmth and durability. Single-ply cashmere can still be lovely as a featherweight layer, but expect it to be more delicate and to need gentler wear.
Why does my cashmere sweater pill?
Pills form when short or loose fibers work free and tangle, usually where there's friction, such as underarms and cuffs. Sweaters spun from shorter, broken fibers pill faster. Even good cashmere pills a little at first. Remove pills gently with a cashmere comb, and only when they appear, since frequent combing thins the knit.
Is a cashmere sweater worth the money?
A well-made one, cared for properly, can be. Long, fine fibers hold their shape and pill less over time. But price predicts quality only up to a point: FIT's Imran Islam says that above a high-quality baseline, extra cost is often brand positioning or design. Judge the knit and the spec line, not just the price.
Does brushed cashmere pill more?
Usually, yes. Brushing raises a soft halo on purpose, and Wirecutter's testing found that more surface fluff typically means more pilling. That doesn't make brushed cashmere low quality. Choose a dense knit with a stated ply or pilling grade, hand-wash it, fold it, and de-pill only when needed.
What's the difference between 7-gauge and 12-gauge cashmere?
Gauge is the number of stitches per inch. A 12-gauge knit is finer, smoother and lighter, good for layering under a blazer. A 7-gauge knit is chunkier and cozier, with more visible texture. Neither is higher quality by default. Gauge describes the style of knit, so judge quality by density, ply and fiber.
