Choosing a genuine mulberry silk pillowcase comes down to two numbers: momme weight and grade. A cheap satin-polyester impostor slides like plastic, traps heat, and pulls moisture from your skin and hair overnight. Real 100% mulberry silk uses long-strand 6A fibers woven tightly enough to let your face glide without friction while naturally regulating temperature — cooler in summer, warmer in winter.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent countless hours cross-referencing momme densities, closure types, wash-test results, and certification data across dozens of silk pillowcase listings to isolate the models that deliver authentic construction without hidden compromises.
This guide breaks down the seven strongest contenders by weave density, fiber grade, and real-world durability so you can pick with clarity. If you’re searching for the actual best 100 mulberry silk pillowcases, start here.
How To Choose The Best 100 Mulberry Silk Pillowcases
Mulberry silk pillowcases vary wildly in weave density, fiber length, and closure design. Three decision points separate an investment piece from a fabric that will fray, snag, or feel rough after five washes.
Momme Weight — The Density Benchmark
Momme (mm) measures fabric weight per unit area. A 19-momme weave is entry-level — soft but sheer enough that you can see your hand through it. A 22-momme weave is the standard for durability with no transparency. A 25- or 30-momme pillowcase feels heavier, drapes with more body, and resists tearing significantly longer. Higher momme also means better temperature regulation because the denser weave slows air exchange without trapping heat.
Fiber Grade — 6A Is The Only Grade Worth Buying
Silk fiber is graded from A through 6A, with 6A representing the longest continuous filaments and the fewest imperfections. Lower grades require more twisting, which creates a rougher surface and more loose ends that pill. Every product on this list uses Grade 6A long-strand mulberry silk. If the listing does not state a grade, assume the silk was sourced from shorter fibers that will degrade faster.
Closure Type — Zipper vs Envelope
A hidden zipper keeps the pillowcase taut and prevents the pillow from shifting overnight, but the zipper tape can scratch sensitive skin if the flap is not fully enclosed. An envelope closure eliminates that risk entirely and makes removal for washing easier, but some envelope designs leave extra fabric that bunches. The ideal choice depends on whether you prioritize zero-shift stability (zipper) or zero-irritation smoothness (envelope).

In‑Depth Reviews
1. DECOLURE Pure Mulberry Silk Pillowcase
DECOLURE delivers the highest momme weight in this lineup — 30 momme of Grade 6A long-strand mulberry silk. That density means zero transparency and a fabric weight that drapes with real body rather than collapsing like a thin sheet. The hidden zipper is stitched with a fabric flap that protects your face from any zipper tape contact, a detail that matters for side-sleepers who press directly against the edge.
Customer feedback consistently highlights the cool-to-the-touch feel that persists through the night. Several buyers mention that the standard size fits pillows snugly — almost too tight — which keeps the surface drum-tight but may put extra stress on the zipper over time. The silver grey color is muted enough to blend with most bedding palettes.
The pillowcase arrives in a rigid gift box with ribbon, making it a viable present without needing extra wrapping. Hand-washing or a gentle machine cycle with zipper closed keeps the fabric smooth. If 30 momme is your target density, this is the most direct path to it.
Why it’s great
- Highest momme (30) in the group for durability
- Zipper flap prevents skin irritation
- Gift-ready packaging included
Good to know
- Standard size fits very snugly
- Single pillowcase only
2. Bella Coterie Luxury Silk Pillowcase
Bella Coterie matches DECOLURE on momme (30) and fiber grade (6A), but leans harder into anti-aging and acne-fighting claims through the natural amino acid profile of pure silk. The weave is exceptionally tight, producing a surface that feels almost starch-smooth without any stiffness. The hidden zipper runs the full width of the short side, and the brand uses upgraded stitching at the seams to reduce the chance of unraveling.
Buyers with standard pillows note that the queen size leaves extra fabric, creating a looser fit than the DECOLURE. That looseness can be an advantage if you prefer a bit of give rather than a drumhead surface. The ivory color is a warm neutral that avoids the clinical look of pure white silk.
The brand offers a 30-day guarantee, which reduces the risk of investing in a high-momme pillowcase sight-unseen. Machine washing on delicate with a mesh bag preserves the weave. If you are prioritizing density and a softer fit tolerance, this is the strongest alternative to the DECOLURE.
Why it’s great
- 30 momme with reinforced stitching
- Good for acne-prone and sensitive skin
- 30-day satisfaction guarantee
Good to know
- Queen size runs loose on standard pillows
- Pricey for a single piece
3. Fishers Finery 25mm Mulberry Silk Pillowcase
At 25 momme, Fishers Finery occupies the space between standard 22-momme offerings and the 30-momme heavyweights. The envelope closure uses an oversized flap that keeps the pillow secure without a zipper — no metal or plastic near your face. The natural white color is undyed, which appeals to buyers who want to avoid even low-impact dyes.
Customers consistent praise the balance between softness and heft; the 25-momme weave is dense enough to resist tearing but not so thick that it feels stiff. The envelope flap is offset, allowing the pillowcase to double as a sham for decorative purposes. Hand-washing with the included mesh bag is the recommended method, and owners report the fabric holds up well after repeated gentle cycles.
Some buyers note that the envelope style leaves a slight fold line where the pillow inserts, which is a minor aesthetic trade-off compared to the seamless look of a zippered case. If you prefer no zipper contact and want a density above the standard 22 momme, this is the mid-point that delivers both.
Why it’s great
- 25 momme offers above-average density without stiffness
- Envelope closure eliminates zipper irritation
- Undyed natural white for sensitive skin
Good to know
- Envelope flap can leave a visible fold line
- Hand-washing recommended for longevity
4. ZIMASILK 22 Momme Silk Pillowcase
ZIMASILK hits the sweet spot of 22 momme — dense enough to be durable and opaque, light enough to stay breathable in warm climates. The ivory color is a warm off-white that resists showing makeup transfer as aggressively as pure white. The hidden zipper is fully enclosed by a fabric flap, so side-sleepers will not feel the metal.
Multiple reviews from buyers with long thick hair report a noticeable reduction in morning tangles and knots after switching from cotton. The 22-momme weave creates just enough friction resistance to let hair slide without feeling slippery. After several months of machine washing in a mesh bag, the fabric retains its shape and the zipper remains functional.
The OEKO-TEX certification adds confidence that the dye chemistry and production process avoid common allergens and heavy metals. The 180-day support window is longer than most competitors, which reduces the risk of buying a mid-weight pillowcase sight-unseen. If you want proven 22 momme performance with a strong guarantee, this is the pick.
Why it’s great
- 22 momme delivers density without weight
- OEKO-TEX certified for safe materials
- 180-day support policy
Good to know
- Single pillowcase only
- Ivory color may not match all bedding sets
5. TheSleepGuard Pure Silk Pillowcase
TheSleepGuard uses a 22-momme 6A weave with an envelope closure that avoids zippers entirely. The ivory white shade is slightly warmer than pure white and resists yellowing over time. The envelope flap is generously sized, so the pillow stays inside even during active sleep.
Customers with sensitive skin specifically mention that the absence of zipper hardware allows them to sleep on either side without irritation. The fabric is described as smooth and cool without the slippery plasticky feel of lower-grade satin. After washing on a gentle cycle with a pH-neutral detergent, the pillowcase maintains its original drape and color.
The brand positions this as dermatologist-recommended, and the OEKO-TEX certification backs up the low-chemical claim. If you have facial eczema, rosacea, or simply want zero hard-contact risk, the envelope design makes this the safest choice in the lineup.
Why it’s great
- Envelope closure avoids all zipper contact
- OEKO-TEX certified, dermatologist-recommended
- Cool-to-touch feel persists through the night
Good to know
- Envelope can leave a visible flap line
- 22 momme is standard density, not premium
6. THXSILK Set of 2 Mulberry Silk Pillowcase
THXSILK gives you two Grade 6A mulberry silk pillowcases with hidden zippers at a price point that undercuts most single-piece competitors. The metallic gold color is distinctive but not garish, and the 19-momme weave (based on customer inference) is lighter than the 22-momme standard. That lighter weight makes it more breathable for hot sleepers but slightly less durable over many wash cycles.
Customer reviews consistently praise the concealed zipper design, which keeps the pillow secure all night without the pillow sliding out. Several buyers mention that the 19-momme density is soft enough for side-sleeping but may show some transparency when stretched. The set comes in a gift-ready package, making it a practical option for replacing both pillowcases at once.
The fabric holds dye well after washing, and the zipper remains functional after multiple machine cycles. If you need two pillowcases immediately and are comfortable with an entry-level momme weight, this set delivers the best per-unit value in the roundup.
Why it’s great
- Two pillowcases for the price of one elsewhere
- Concealed zipper keeps pillow in place
- Breathable and cool for warm sleepers
Good to know
- Lighter 19 momme may show through when stretched
- No explicit momme weight listed
7. Bare Home 100% Mulberry Silk Pillowcase 2-Pack
Bare Home offers two 19-momme Grade 6A silk pillowcases with hidden zippers, making it a direct competitor to THXSILK with a slightly more established brand presence. The grey color is a true neutral that works with most bedding. The 19-momme weave is the lightest in the roundup, which means maximum breathability but the least resistance to long-term abrasion.
Buyers upgrading from cotton report a clear difference in hair smoothness and skin hydration. Several customers note that the pillowcase looks like new after ten or more wash cycles, suggesting the 6A long-strand fibers hold up well despite the lower momme weight. The zipper is fully hidden and does not scratch surrounding sheets — an issue cited with some competing brands.
Bare Home includes a 30-night satisfaction window and customer service that responds quickly to quality concerns. If you want a two-pack at a friendly entry point and are willing to trade some density for breathability and value, this is a strong option.
Why it’s great
- Two pillowcases at a competitive price point
- Hidden zipper avoids sheet scratching
- Stays cool and breathable all night
Good to know
- 19 momme is entry-level density
- Less durable over many years compared to 22+ momme
