The Secret Language of Softness: What “Micron” Really Means in Cashmere
If Luxury Had a Metric, It Would Be This One
Cashmere is one of those rare things in life that feels exactly how it looks—soft, elevated, and just a little addictive. But behind that famously cloud-like texture is a detail so small, it's practically invisible to the eye: the micron.
Don’t let the science-y name fool you—knowing what micron means might be the smartest style move you make all season. Here’s how this tiny measurement unlocks the secret to truly exceptional cashmere.
What Is a Micron, and Why Does It Matter?
Let’s break it down: a micron (short for micrometer) is a measurement used to define how fine a fibre is—and in cashmere, fineness = softness.
A single strand of human hair is about 50 to 70 microns wide.
Premium cashmere? Try 14 to 18 microns.
Translation: cashmere fibres are ridiculously fine—that’s why they feel so silky, weightless, and luxe on your skin.
📌 Fun fact: The word “micron” comes from the Greek mikros, meaning “small.”
Micron Math: The Lower, the Softer
So here’s the deal—the lower the micron count, the softer, smoother, and more luxurious the cashmere feels. That’s because finer fibres bend more easily, creating that signature softness and drape you love.
How to Picture It: Human Hair vs. Cashmere Fibre
Want to really grasp the difference? Imagine this: a few strands of cashmere could fit inside one human hair. That’s how fine it is. And that’s exactly why a high-quality cashmere jumper feels so unbelievably good, without any of that scratchy wool drama.
The Sweet Spot: Micron Ranges for Cashmere Apparel
For everyday luxury—that sweater you reach for on chilly Auckland mornings or windy Wellington nights—the sweet spot is 15.5 to 19 microns. This range offers the perfect balance of softness, warmth, and durability.
Under 16 microns → Ultra-luxe, rare
16–19 microns → Premium quality, perfect for knitwear
19+ microns → More textured, often blended with other fibres
Grades A, B, and C: The ABCs of Cashmere Quality
You’ve probably seen brands talk about Grade A cashmere. What they’re really referring to is the micron count, plus other fibre factors like length, crimp, and guard hair content.
Grade A: Micron count below 16.5 – dreamy soft, lightweight
Grade B: 16.5 to 19 microns – still luxe, slightly more robust
Grade C: Over 19 microns – coarser, more suitable for durable or blended styles
Heads up: Not every brand uses these grades, and not every label tells the whole story. The best test? Touch it. Wear it. Feel it. If it’s soft enough to make you never want to take it off, chances are, it’s the real deal.
A Micron of Difference, A World of Luxury
In a world of fast fashion and flashy branding, cashmere remains quietly confident—and micron count is its whisper of distinction.
