The short answer: Mulberry silk and habotai silk are not the same kind of thing. Mulberry describes the type of silk — produced by the Bombyx mori silkworm, fed exclusively on mulberry leaves, which gives a filament longer, finer, and more even than any other. Habotai describes the type of weave — a fine, lightweight plain weave originally from Japan, prized for its soft, fluid drape. The two terms describe different attributes, and most luxury habotai scarves you'll come across are in fact made from mulberry silk. The right question is not "mulberry or habotai" but: which mulberry-silk weave is right for what you want to wear?
If that distinction is new to you, you are in good company. The two words have been used so interchangeably in fast-fashion product listings that even experienced shoppers struggle to tell what they are actually buying. This guide takes the confusion apart — clearly, with a little science, and without keyword-stuffing. By the end of it, you will know how to read a silk label, what to ask before you spend, and how to spot real mulberry silk in less than a minute.
Mulberry silk: the silk that defines the category
Mulberry silk is the silk produced by Bombyx mori — the domesticated silkworm, descended from generations bred for one purpose only: to spin a long, even, uninterrupted filament of silk fibre. Unlike wild silkworms, Bombyx mori is fed exclusively on the leaves of the white mulberry tree. That single dietary fact is the reason mulberry silk has the qualities it does.
A mulberry silkworm's diet of mulberry leaves produces a silk fibre that is:
- Longer — a single continuous filament can run 600 to 900 metres without a break.
- Finer — diameter typically 10–13 microns, finer than a human hair by a wide margin.
- More even in colour — naturally creamy white, with no irregular pigmentation from a varied forest browse.
- Stronger — a higher tensile strength than wild silks, which is why mulberry silk garments survive decades.
- Smoother to wear — no microscopic burrs or short fibres to catch on skin or hair, which is why it is considered hypoallergenic.
Mulberry silk is the silk of luxury fashion houses, the silk used for fine wedding gowns, the silk inside the world's most expensive pillowcases. When a brand says "100% silk" without qualification, in a luxury context, they almost always mean mulberry silk — though it is always worth checking.
There are other silks. The most common alternatives are tussah (sometimes spelled tasar), eri, and muga — all produced by wild silkworms feeding on a range of forest leaves. These are real silks, and beautiful in their own way, but they tend to be coarser, less even in colour, and more textured. They have their place in slow-fashion and craft contexts; they are not the silk you want for a scarf that should feel like liquid against the skin.
Habotai: a weave, not a fibre
If mulberry is the silk, habotai is what you do with it. Habotai (sometimes written habutai or hābutae) is a plain-weave structure that originated in Japan; the name translates roughly as "soft as down." It is the simplest of weaves — single weft threads going over and under single warp threads — but worked at a very fine count, with very lightly twisted silk yarn.
The result is a fabric that is:
- Lightweight — typically 5 to 12 momme (more on momme in a moment).
- Smoothly fluid — the loose twist and plain weave allow the fabric to fall like water.
- Softly lustrous — a subtle, low-glare sheen, rather than the high shine of charmeuse or satin.
- Slightly sheer — at lower weights, you can see your hand through a single layer held up to the light.
- Quick to take dye — which is why habotai is the weave of choice for hand-dyed silk scarves.
Habotai was originally a kimono-lining fabric in Japan, prized because it did not pull on the silk of the outer garment. Today, it is the standard weave for fine silk scarves and lightweight blouses, and the canvas for most of the hand-dyed silk you will encounter outside of saris.
It is important to be clear: habotai can be made from non-mulberry silks, or even — at the cheap end — from synthetic fibres pretending to be silk. The label "habotai" alone tells you nothing about the underlying material. The combination mulberry silk, habotai weave is the one that tends to mark a piece you would want to keep.
So why does "mulberry vs habotai" come up at all?
Because most silk labels are vague. A scarf described only as "100% silk" leaves you guessing at both the source and the weave. A scarf described as "habotai silk" tells you the weave but not the fibre. A scarf described as "mulberry silk" tells you the fibre but not the weave. To buy with confidence, you want to know both.
A well-described luxury silk scarf will say something like: 100% mulberry silk, habotai weave, 8 momme, hand-dyed in Vietnam. That single sentence tells you everything — the silk type, the weave, the weight, and how the colour was applied.
A short guide to silk weaves you might also meet
While habotai is the most common weave for scarves, mulberry silk can be woven in several other ways. Knowing the names changes how you shop.
Charmeuse is a satin weave: the warp threads pass over four wefts at a time before going under one, which creates the famous high-shine front and matte back. Charmeuse drapes more heavily than habotai and is what you most often see in silk slip dresses, evening gowns, and luxury bedding.
Crepe de chine is woven from tightly twisted yarn, which gives it a faint pebbled texture and almost no shine. It is heavier and more forgiving than habotai — popular for blouses you actually want to iron occasionally.
Chiffon is even lighter than habotai, with a deliberate slight crinkle in the surface. It is sheer and floaty, used for layered evening wear and very delicate scarves.
Organza is the crisp one — stiff, transparent, almost paper-like. It holds shape; it does not drape. It is the weave used for structured bridal overlays.
Silk satin is woven the same way as charmeuse but with a heavier, more lustrous result. The two terms are often used interchangeably.
For a scarf you want to wear daily — knotted, draped, packed flat in a bag, pulled out for an evening — habotai is the most considered choice. The other weaves have their moments.
The variable that actually matters — momme
If you are choosing between two mulberry-silk habotai scarves, the most useful number on the label is momme (pronounced moh-mee). Momme is a Japanese unit of weight per unit area — the higher the momme, the heavier and more substantial the silk.
A rough guide:
- 5–6 momme — very light, semi-sheer, almost cloud-like. Best for delicate layering and evening scarves.
- 8–10 momme — the sweet spot for hand-dyed silk scarves. Substantial enough to drape beautifully and take rich dye, light enough to fold into a clutch.
- 12–14 momme — heavier scarves, large shawls, wedding wraps that need to keep their shape across the shoulders.
- 16–19 momme — charmeuse blouses, slip dresses, fine silk pillowcases (sleep specialists often go to 22 momme).
- 22 momme and above — substantial silk for tailoring, bedding, heavy curtains.
For an everyday silk scarf or shawl, anything below 5 momme is too flimsy to last; anything above 14 momme starts to feel less like a scarf and more like a wrap. The 8–10 momme range is what most considered silk scarf brands settle on — including ours.
"Mulberry is the silk. Habotai is the weave. The combination is what marks a scarf worth keeping."
How to spot real mulberry silk in 60 seconds
Three quick tests, in roughly this order.
The hand test. Real mulberry silk warms quickly against the skin — within seconds — and stays warm. Polyester pretending to be silk stays cool and slightly slippery. Hold the fabric loosely in your palm for ten seconds; if it does not warm, it is not silk.
The slub test. Look closely at the weave under a bright light. Real mulberry silk is remarkably even — almost flawless, because the Bombyx mori filament is so consistent. Wild silks (tussah, eri) show occasional thicker fibres called slubs. Synthetic silks show perfect, slightly plastic regularity. If you see soft natural variation but no slubs, you are very likely looking at mulberry silk.
The burn test (only if you have an offcut — never on a finished piece). Hold a single thread to a flame. Real silk burns slowly with a smell like burning hair, leaving a fine crumbly black ash you can crush between your fingers. Polyester melts into a hard plastic bead and smells chemical. Wool burns similarly to silk but smells sharper. The burn test is the only definitive proof — and the one most often skipped, because nobody wants to set fire to a scarf they have just bought.
What we use at Silk & Bears, and why
All Silk & Bears scarves are 100% mulberry silk, woven in the habotai tradition, in the weight range that gives a hand-dyed scarf its signature liquid drape. The silk is hand-dyed individually in Vietnam, in workshops where the craft of hand-dyed silk has been kept alive for generations. We do not dye the silk ourselves — the artisans do. We champion their work and bring it to you in a form that travels.
We chose mulberry silk because nothing else takes hand-dyeing this beautifully. The Bombyx mori filament is so even, and so absorbent, that the colour lives in the silk rather than sitting on top of it — which is why no two of our scarves are exactly alike, and why the colour does not fade with wear the way printed colour does. We chose habotai weave because it lets the colour breathe and the fabric move. Together, the combination is the reason a silk scarf can feel both substantial and weightless in the same moment.
When you next buy silk — three questions to ask
In this order:
- What kind of silk? Mulberry is the answer you want.
- What weave? Habotai for scarves; charmeuse for slip dresses and pillowcases; crepe de chine for blouses.
- What weight, in momme? 8–10 momme for a daily silk scarf; 19–22 for a pillowcase you want to keep for years.
If a label does not tell you all three, ask. A brand that does not know — or will not say — is one to walk away from.

Frequently asked questions
Is habotai silk real silk?
Yes — habotai is a weave, not a substitute for silk. Most habotai you will encounter is genuine silk, and the better pieces are 100% mulberry silk. Cheap "habotai" labelled scarves are sometimes polyester pretending to be silk; the hand test, slub test, and burn test described above will tell you which.
Is mulberry silk the same as habotai silk?
No. Mulberry describes the fibre (the silk itself, produced by the Bombyx mori silkworm fed on mulberry leaves). Habotai describes a way of weaving silk into fabric (a fine, lightweight plain weave). A scarf can be both — and the best ones are.
Which is better for scarves: habotai or charmeuse?
Habotai is lighter, more fluid, and takes hand-dyeing more beautifully — making it the standard for fine silk scarves you tie or drape. Charmeuse is heavier and shinier, better suited to slip dresses, pillowcases, and luxury sleepwear. Neither is "better" — they are different tools.
What is the best weight for a silk scarf?
For an everyday silk scarf, look for 8–10 momme. Lighter than that and the silk feels insubstantial; heavier and it starts to behave like a wrap rather than a scarf. A wedding shawl can sit at 10–14 momme to drape properly across the shoulders.
How can I tell if my silk is real?
Three quick tests: warm it in your palm for ten seconds (real silk warms; polyester stays cool), look at the weave under bright light (real silk is remarkably even with no plastic regularity), and — only on a thread from an offcut — burn it (real silk smells like hair and leaves crumbly ash; polyester melts into a chemical-smelling bead).
Can mulberry silk be habotai?
Yes — most fine habotai scarves are made from mulberry silk. The terms are not exclusive. A well-described luxury scarf will name both: 100% mulberry silk, habotai weave, along with the momme weight.
