A cashmere blend mixes cashmere with another fibre, usually wool, so it costs less and stands up to more wear, while pure cashmere is softer against skin and more delicate. Neither is the wrong choice. Buy pure cashmere for pieces that touch bare skin and see little friction, and a stated-percentage blend for pieces that work hard.
The worry behind this question is usually being sold less cashmere than the name suggests. That worry is fair, but the fix is not to avoid blends. It is to read the percentage. A blend that tells you its ratio is a design decision you can judge. A label that only says "cashmere blend" is the one to walk away from.
What is a cashmere blend?
A cashmere blend is a yarn or fabric where cashmere is one of two or more fibres, and the label should give each one as a percentage. The cashmere share can be small or large, so "blend" on its own tells you little. What makes the cashmere part cashmere is fineness: under the US labelling rule quoted in Wikipedia's entry on cashmere wool, fibre sold as cashmere must average no more than 19 microns across. Wool partners are usually thicker, which is why they add body and resist rubbing. Our two beanies show the range. The Alashan Cashmere-Blend Beanie is 10% cashmere and 90% wool, knitted in two layers to keep wind out. The Cashmere-Blend Cloud Beanie carries between 31 and 50% goat cashmere from Inner Mongolia, for foreheads that feel every wool hat. Same word on the label, different hats.
What does a blend change, and what does it keep?
A wool partner adds spring, shape and resistance to rubbing, and the cashmere softens the hand. Cashmere's softness comes from how fine it is, and the same fineness makes it pill sooner where it rubs and relax out of shape in pieces that get pulled. Wool is springier and coarser. Wikipedia's wool entry puts the itch line for coarse fibres at about 30 to 32 micrometres and above, so the grade of the wool partner decides how a blend feels on skin as much as the cashmere share does.
A blend is also cheaper because cashmere is scarce. The same cashmere entry gives the average yield as 150 grams per goat per year, which is why the share of cashmere moves the price more than anything else on the label.
Cashmere blend vs pure cashmere, side by side
Pure cashmere wins on softness and blends win on durability and price. Here is how they compare in use.
| Property | Cashmere blend (with wool) | 100% cashmere |
|---|---|---|
| Softness on skin | Depends on the ratio and the wool grade | Softest, no prickle from the fibre |
| Wear and pilling | Wool resists rubbing; pills less | Pills sooner where it rubs |
| Shape | Springs back after stretching | Relaxes and drapes over time |
| Price | Lower, moves with the cashmere share | Higher, moves with fineness |
| Best for | Throws, hats in wind, daily outer layers | Socks, pieces worn against bare skin |
Where we use pure cashmere and where we use a blend
We use pure cashmere where skin is bare and friction is low, and a blend where a piece is sat on, pulled or worn in wind. The 100% Cashmere Bed Socks are listed as 100% goat cashmere on the maker's product sheet, 40 g a pair, knitted in Inner Mongolia. They meet bedding and carpet, not pavements, so pure cashmere makes sense, and the page still warns that cashmere can pill at the heel.
The Herringbone Cashmere-Blend Throw is 10% cashmere and 90% lambswool, about 800 g and 145 by 200 cm, woven in herringbone with fringed ends. A throw is sat on, tugged and folded over a sofa arm every evening. Lambswool carries that load, and the cashmere takes the edge off the hand. The beanies sit between the two: the 10% blend for a crosswind on a bridge, the Cloud for a forehead that prickles easily.
How do you read a blend label?
Check three things: whether percentages are given, which fibre leads, and whether the cashmere words describe content or only feel.
- Percentages. "10% cashmere, 90% wool" is a label you can judge. "Cashmere blend" with no numbers is not.
- The leading fibre. Wool or lambswool as the partner behaves like wool. A synthetic-led blend with a few percent of cashmere is a different, cheaper product.
- Feel words. "Cashmere touch" and "cashmere feel" describe texture, not fibre content. Look for the word cashmere next to a number.
Grade still matters inside pure cashmere. Our guide on how to spot quality cashmere covers the checks, and Mongolian wool vs cashmere explains the two fibres from the animal up. Everything we make with cashmere is in the cashmere edit, with the exact content on each page.
FAQ
Is 10% cashmere worth it?
It depends on what you want it to do. At 10%, cashmere softens the hand of a wool piece but does not make it feel like pure cashmere, and if wool makes you itch, a 10% blend may still itch. For a hat in wind or a throw on a sofa, that trade is a good one. For bare skin, choose a higher share or pure cashmere.
Does a cashmere blend pill?
Yes, a little, like most knits and soft weaves. A wool-led blend usually pills less than pure cashmere because the thicker fibre resists friction, but cuffs, collars and the spot where a sofa arm rubs will still show some fuzz. A cashmere comb lifts it off in a few light passes. Pilling is surface wear, not a sign the fibre is poor.
How should you wash a cashmere blend?
The same way as pure cashmere: cool to lukewarm water with a wool detergent, or dry cleaning, then press the water out in a towel and dry it flat away from heat. Skip the dryer and the hanger. A blend tolerates daily wear better than pure cashmere, but it does not tolerate hot water or tumble drying any better.
Is a cashmere blend warmer than wool?
Not by much at the same weight. Warmth comes mostly from how much fibre there is and how it traps air, so a thick double-layer wool knit can be warmer than a thin cashmere blend. What the cashmere changes is softness against skin. If warmth is the goal, compare the weight in grams and the knit before the cashmere share.
