Cashmere

Cashmere is the fine, downy undercoat a cashmere goat grows for winter. It’s combed out rather than shorn, and each goat produces only a few ounces per year.

That scarcity sets the price, and the price explains most of what can go wrong on the label.

Is Cashmere Just Fine Wool?

Close! The difference is the animal, not the chemistry. Cashmere is keratin, the same protein family as sheep’s wool, grown by a different goat at a much finer diameter.

US labeling rules only allow the word “cashmere” for fiber from the cashmere goat’s undercoat averaging 19 microns or finer. For comparison, fine merino generally runs about 17 to 24 microns, and the prickle threshold for wool sits near 30. Cashmere lives comfortably under that line, which is a big part of why it feels so soft.

Why Is Cashmere So Soft?

Fiber diameter first, then crimp. Fibers this fine bend against your skin instead of pressing into it, so the prickly feeling that makes coarse wool itch mostly never happens.

Cashmere also carries a natural crimp that traps air, which is why a cashmere sweater can insulate far beyond its weight. And moisture handling works the way it does in wool: vapor moves into the fiber while the surface feels dry to the touch.

Why Does Cashmere Pill?

The same qualities that make cashmere soft also make its surface delicate. The fibers are short, and soft knits are spun with a low twist to keep that gentle feel, so loose fiber ends can work their way to the surface and tangle wherever friction repeats.

Quality mostly comes down to fiber length and twist, and neither appears on a swing tag. That means a budget cashmere sweater and an expensive one can read identically on the label and still age very differently, which is the same lesson acrylic teaches at the other end of the price range.

How Do You Tell Real Cashmere?

Unfortunately, not by touch. Feel and sheen can be engineered in blends and even in synthetics, so the practical checks are simpler ones:

• Read the fiber line, with percentages. “Cashmere blend,” “cashmere-touch,” and “cashmere-feel” with no number are marketing terms, not composition.
• Consider the price. The raw fiber is scarce and expensive, so a very cheap “100% cashmere” garment deserves some healthy skepticism.
• Remember that labels sometimes mislead. In the EU’s inspection campaign published in June 2026, blends of natural and man-made fibers failed their label claims 64% of the time, and premium fibers carry the strongest incentive to overstate.

Because blend claims are the least reliable line on a tag, Lynen commissions independent accredited laboratories to check them. Cashmere is where that check matters most, since everything about the claim is invisible when you’re standing in the store.

If your skin reacts to certain fabrics regularly, talk with your dermatologist. This is general wellness information drawn from published research, not medical advice.

How Should You Care for Cashmere?

Wash cashmere rarely, in cool water, and gently, following the same rules as wool: no wringing, dry flat, and store it clean and folded, since moths eat protein fibers and a heavy knit can stretch on a hanger.

When pills appear, remove them with a fabric shaver rather than pulling them off by hand.

Give cashmere a day of rest between wears and a good sweater can recover for years. It’s a small routine for a garment that gives a lot back!
