# What is cashmere, and is it worth it Source: Snaza Journal, https://snaza.app/journal/what-is-cashmere/ Publisher: Snaza Topic: Fabrics and patterns Published: 2026-09-26 Updated: 2026-09-26 What is cashmere: the goat undercoat it comes from, why it costs more than wool, how to judge a cashmere sweater in the store, and how to keep it soft for years. ## Quick answer > Cashmere is the fine, soft undercoat fiber of cashmere goats, combed or sheared during the spring molt and separated from the coarse outer hair. Under US labeling rules the fibers must average 19 microns or less. Each goat gives only a small amount a year, which is why cashmere costs more than sheep's wool. It is light, warm and soft, but pills and needs gentle care. Two sweaters on a store table look almost the same. One label says merino wool, the other says cashmere, and the second price tag is a good deal higher. It is fair to ask what is cashmere, really, and whether the difference is something you will feel after the first month. The answer is that cashmere is a genuinely different fiber, with real advantages and a few real weaknesses, and that the label alone tells you much less about quality than most people assume. This guide covers where cashmere comes from, why it is expensive, how it compares to wool and merino, how to judge a cashmere sweater before you buy, and how to care for it so it stays soft. ## What cashmere is made of Cashmere comes from goats, not sheep. Cashmere goats grow a double coat: long, coarse guard hairs on the outside and a fine, downy undercoat beneath that keeps them warm through cold winters on high plateaus. In spring, as the weather warms, the goats molt that undercoat. Herders collect it by combing, which yields cleaner, finer fiber, or by shearing, which is faster but mixes in more coarse hair. The raw fiber is then washed and mechanically dehaired to separate the soft down from the guard hair, and only then spun into yarn. The name comes from Kashmir, where the fiber has been woven into shawls for centuries. Today most raw cashmere comes from China and Mongolia, with Afghanistan and other Central Asian countries behind them. In the United States, the Federal Trade Commission sets what can be called cashmere: the fine dehaired undercoat of the cashmere goat, with an average diameter of no more than 19 microns and very little coarse fiber mixed in. Goat fiber that does not meet those limits must be labeled as wool. ## Why cashmere is so expensive The main reason is yield. A single cashmere goat produces only about 150 to 300 grams of usable fiber a year, roughly a third to two thirds of a pound, while a sheep can grow several kilograms of fleece. It can take the down of more than one goat to knit a single sweater. On top of that, combing is slow handwork, and dehairing and sorting remove a large share of what is collected. Cost also reflects quality differences you cannot see on a label. Long, fine fibers from the best grades spin into stronger, smoother yarn that pills less, and they cost the mill more. Cheap cashmere is often made from shorter, coarser fibers or knitted loosely to use less yarn, which is why a bargain sweater may feel lovely in the store and look tired after a season. Overgrazing by growing goat herds has also damaged grasslands in Mongolia and China, which is one reason some buyers look for traceable or recycled cashmere. **Worth remembering** 1. One goat yields only about 150 to 300 grams of usable fiber a year, which is the main reason for the price. 2. US law limits cashmere to fine dehaired undercoat averaging no more than 19 microns. 3. A very fuzzy surface in the store can mean short, heavily brushed fibers that pill first. 4. Good cashmere feels dense and springy, and a gently stretched cuff snaps back promptly. ## Is cashmere wool? Cashmere vs wool and merino In everyday speech, and under the US wool labeling law, cashmere counts as a specialty wool: an animal hair fiber in the same family as sheep's wool, alpaca and mohair. It shares wool's basic behavior. It is a protein fiber with a scaly surface, it holds warmth when damp, resists odor and can felt and shrink if washed hot with agitation. The differences are in fineness and feel. Cashmere fibers are finer than ordinary wool and have less crimp, so cashmere feels softer, lighter and more fluid, with a gentle halo. Is cashmere better than merino? It depends on what you need. Fine [merino wool](https://snaza.app/journal/merino-wool/) can be as fine as cashmere and is more durable, less prone to pilling and easier to wash, which makes it better for base layers, travel and everyday sweaters that work hard. Cashmere wins on softness, loft and warmth for its weight, which makes it better for sweaters, scarves and wraps worn for comfort rather than exertion. **Cashmere and merino compared** | Quality | Cashmere | Fine merino | | --- | --- | --- | | Source | Downy undercoat of cashmere goats | Sheep | | Feel | Softer, lighter, more fluid, with a halo | Can be as fine as cashmere | | Washing | Hand wash lukewarm, felts with heat and rubbing | Easier to wash | | Durability and pilling | Pills more, needs gentler use | More durable, pills less | | Best for | Sweaters, scarves and wraps worn for comfort | Base layers, travel and hardworking sweaters | ## Is cashmere warm, and is it itchy? Cashmere is very warm for its weight. The fine, lofty fibers trap a lot of still air, so a thin cashmere sweater can feel as warm as a much bulkier wool one. That makes it excellent for layering under a coat, and for people who dislike heavy knits. Because it breathes like wool, a cashmere sweater is also comfortable over a wider range of temperatures than a synthetic fleece. Good cashmere is not itchy for most people. Itch from wool comes mainly from coarse fibers pressing into the skin, and cashmere's fibers are too fine for that. If a cashmere piece does prickle, it usually contains coarser fibers or guard hair, or it is a blend with wool. Some people are sensitive to lanolin or dyes rather than the fiber itself; if you react to all animal fibers, a silk or cotton layer underneath helps. ## How to judge a cashmere sweater Start with the label. By law it must give the fiber percentages, so 100% cashmere or all cashmere is pure, while a cashmere blend will list something like 70% wool, 30% cashmere. Blends can be good value, but they are a different product. Then use your hands. Good cashmere feels soft but also dense and springy. Gently stretch a small section of the cuff or hem and release it: it should spring back promptly. A loose, floppy knit that stays stretched will lose its shape. Look at the surface against the light. A very fuzzy, fluffy surface in the store can mean short fibers that have been heavily brushed, and short fibers are the ones that pill first. A smoother, cleaner surface with a light halo is usually the better sign. Two ply yarn, where two strands are twisted together, is more durable than single ply for everyday sweaters. Finally, check the seams and ribbing at the cuffs and hem: well made knits have neat, linked seams and ribs that recover when stretched. ## How to wear a cashmere sweater A cashmere sweater looks best when it is allowed to be quiet. A crew neck or V neck in navy, gray, camel, cream or black works over a collared shirt, a T shirt or alone with good trousers. For men, a V neck cashmere sweater over an oxford shirt with gray trousers is a classic office look, and a crew neck over a T shirt with dark jeans works on weekends. For women, a fine crew or turtleneck under a tailored coat, or a relaxed cardigan over a slip dress, uses cashmere's drape well. Cashmere scarves, wraps and shawls are the easiest way into the fiber and last well because they are not rubbed at the elbows and sides. A pashmina shawl is traditionally a fine cashmere shawl from the Himalayan region, but the word is not legally defined in the US, and shops use it for everything from fine cashmere to cashmere and silk blends to viscose. Read the fiber content rather than the name. ## Caring for cashmere Cashmere does not need washing after every wear. Air it overnight on a flat surface or chair back and it will freshen. When it does need a wash, most knitted cashmere can be hand washed in lukewarm water with a wool detergent and dried flat; our guide to [washing cashmere](https://snaza.app/journal/how-to-wash-cashmere/) gives the full method. Getting cashmere wet is not the problem. Heat combined with rubbing or wringing is what felts and shrinks it. Some pilling is normal, especially where arms rub the body, and usually settles down after the first few washes as loose short fibers work out. Remove pills gently with a cashmere comb or fabric shaver, as explained in our guide to [removing pilling](https://snaza.app/journal/how-to-remove-pilling-from-clothes/). Store cashmere folded, never on a hanger, and clean before storing, because clothes moths favor animal fibers with food or perspiration on them. Our guide to [storing knitwear](https://snaza.app/journal/how-to-store-knitwear/) covers moth prevention. ## Questions people ask ### Is it bad if cashmere gets wet? No. Cashmere can be washed in water and rain will not harm it. The damage comes from hot water, rubbing, wringing or tumble drying, which can make the fibers lock together and shrink. If a sweater gets soaked, press out the water in a towel and dry it flat away from direct heat. ### What are the disadvantages of cashmere? Cashmere pills more than many wools, is less resistant to abrasion at elbows and cuffs, needs gentle washing and attracts clothes moths. It is also expensive, and quality varies widely at every price. For hard wearing everyday layers, merino is often the more practical choice. ### Is cashmere a fabric or an animal? Cashmere is a fiber from an animal, the cashmere goat, rather than an animal of its own or a type of weave. The fiber is spun into yarn and then knitted into sweaters or woven into fabrics for scarves, coats and suits. ### What does baby cashmere mean? Baby cashmere refers to fiber from young goats, usually the first combing, which tends to be especially fine and soft. There is no legal US definition beyond the general cashmere rule, so the term is a maker's claim rather than a certified grade. Very fine fiber can also be a little less durable. ## Sources - [Cachet of cashmere: complying with the Wool Products Labeling Act, Federal Trade Commission](https://www.ftc.gov/business-guidance/resources/cachet-cashmere-complying-wool-products-labeling-act) - [Cashmere wool, harvesting, production and environmental issues (Wikipedia)](https://en.wikipedia.org/wiki/Cashmere_wool) - [What is merino wool, including fleece yields compared with cashmere, The Woolmark Company](https://www.woolmark.com/fibre/what-is-merino-wool/) - [A guide to cashmere quality, fiber length and ply, Luca Faloni](https://lucafaloni.com/en/us/lf-journal/all-you-need-to-know-about-cashmere-a-guide-for-the-connoisseur) --- This guide is part of the Snaza Journal, published by Snaza.
