A silk pillowcase is worth comparing by more than the word “mulberry.” Fabric density, pillow size, closure design, and how the seams survive repeated washing decide whether the case still feels luxurious months after the first night.
A sound decision about silk pillowcase brand comparison accounts for fit, construction, fabric or fill, care, and realistic daily use.
The five cases here cover 19-, 22-, and 25-momme silk where weight is specified, plus Standard, Queen, and King sizing. Fishers Finery is the densest no-zipper option, ZIMASILK is the lighter Queen zipper pick, Blissy sits in the 22-momme middle, LILYSILK gives Standard pillows a defined YKK zipper, and Brooklinen is the King-size envelope specialist.
Claims about pillowcases and skin sensitivity should be separated from medical advice and judged alongside fit, materials, hygiene, and individual symptoms.

Silk Pillowcases at a Glance
| Case | Stated silk weight | Reviewed size | Closure | Main tradeoff |
|---|---|---|---|---|
| Fishers Finery | 25 momme | Queen 20 x 30 in | Offset side-entry / envelope | Most demanding care |
| ZIMASILK | 19 momme | Queen 20 x 30 in | Hidden zipper | Lighter fabric and heavy wash wrinkles |
| LILYSILK | 19 momme | Standard 20 x 26 in | Hidden YKK zipper | Zipper-seam durability concerns |
| Blissy | 22 momme | Standard 20 x 26 in | Secure closure | Snug fit for some pillows |
| Brooklinen | Not stated | King 20 x 37 in | Envelope | Less direct density comparison |
Momme is only one variable: A higher momme number generally means denser silk, but a case can still fail at the zipper seam or fit poorly. Our guide to what makes a silk pillowcase high quality explains why construction belongs beside fabric weight.
For cooling pillowcase fabrics, fabric weight, airflow, moisture handling, insulation, and room temperature all affect the result.
Our Five Picks
1 / 5
Fishers Finery 25 Momme Silk Pillowcase
Material
Grade 6A mulberry silk on both sides
Weight
25 momme
Size
Queen 20 x 30 in
Closure
Offset side-entry envelope
Fishers Finery has the densest clearly specified silk among these picks. The queen case uses 25-momme Grade 6A long-strand mulberry silk on both sides and avoids a zipper with an offset side-entry, envelope-style closure.
That combination gives it a distinct role. You get more fabric density than the 19- and 22-momme options without adding zipper hardware near the face or a seam that can become a mechanical failure point. The case feels substantial and smooth and fits securely.
Care is the tradeoff for that density. Tumble drying can reduce the silk's luster, and the case may need ironing after washing. Choose Fishers Finery if you want the most substantial silk here and are willing to treat it like delicate bedding.
Why It Works
- 25 momme is the highest stated silk weight in this group.
- Grade 6A mulberry silk covers both sides.
- The envelope-style side entry avoids zipper hardware.
What To Keep In Mind
- Do not assume normal dryer heat is safe.
- Substantial silk comes with a more deliberate laundry routine.
2 / 5
ZIMASILK 19 Momme Silk Pillowcase
Material
Grade 6A mulberry silk on both sides
Weight
19 momme
Size
Queen 20 x 30 in
Closure
Hidden zipper
ZIMASILK is the lighter Queen-size real-silk option. The reviewed case measures 20 by 30 inches, uses 19-momme Grade 6A mulberry silk on both sides, and closes with a hidden zipper.
The lighter 19-momme construction is not automatically worse than denser silk; it simply has less fabric weight. The case has a genuine silk feel and fits some Queen pillows securely, but washing can leave heavy wrinkles, thicker inserts can fit tightly, and replacement may be needed after about a year of frequent use.
Temperature comfort varies too. The case is breathable but can still feel hot. Silk should not be treated as guaranteed overnight cooling.
Why It Works
- Real Grade 6A mulberry silk in a lighter 19-momme construction.
- Double-sided silk keeps the surface consistent when flipped.
- Hidden zipper keeps the pillow enclosed.
What To Keep In Mind
- 19 momme feels lighter than 22- or 25-momme silk.
- Washing can leave noticeable wrinkles.
- A snug Queen fit can compress thicker pillows.
3 / 5
LILYSILK 19 Momme Silk Pillowcase
Material
Grade 6A mulberry silk on both sides
Weight
19 momme
Size
Standard 20 x 26 in
Closure
Hidden YKK zipper
LILYSILK is the most clearly defined Standard-size zipper option. The case measures 20 by 26 inches, uses 19-momme Grade 6A mulberry silk on both sides, and specifies a hidden YKK zipper.
The surface feels smooth and cool. The important drawback is not the silk itself but the zipper area, which can rip after repeated or even limited use. Gentle washing in a mesh bag and line drying reduce strain on the case.
That mixed durability makes this a fit-specific choice rather than a default winner. Buy it when you want a 20-by-26-inch Standard case and prefer a zipper, then watch the closure seam during routine washing.
Why It Works
- Exact Standard dimensions suit a 20-by-26-inch pillow.
- Hidden YKK zipper gives a secure, clearly specified closure.
- The silk has a smooth, cool surface.
What To Keep In Mind
- The zipper seam is the main failure point.
- A Queen pillow needs a larger size.
4 / 5
Blissy 22 Momme Silk Pillowcase
Material
Grade 6A mulberry silk
Weight
22 momme
Size
Standard 20 x 26 in
Sizes
Standard, Queen, King
Blissy occupies the middle ground between 19- and 25-momme silk. The reviewed Standard variant uses 22-momme Grade 6A mulberry silk and measures 20 by 26 inches, with other sizes available in the product family.
The case feels distinctly smoother than polyester satin, sleeps cool for many people, and holds up through repeated washing when handled carefully. The difference from a good satin case will not feel dramatic to everyone.
Fit deserves attention. The Standard case can feel snug, so a thick pillow may need the next size up. Pillow loft matters as much as the label.
Why It Works
- 22 momme provides a useful density step above the 19-momme choices.
- Grade 6A mulberry silk is the stated material.
- Size variants cover Standard, Queen, and King pillows.
What To Keep In Mind
- Thick pillows may need the next size up.
- Its advantage over a good satin case depends on how much you notice the real-silk feel.
5 / 5
Brooklinen Mulberry Silk Pillowcase
Material
Mulberry silk
Size
King 20 x 37 in
Closure
Envelope
Care
Cold wash and air dry
Brooklinen is the King-size specialist in this group. Its mulberry-silk case measures about 20 by 37 inches and uses an envelope opening, making it the natural choice for sleepers who want extra pillow length without zipper hardware.
The case has a substantial real-silk feel and cool surface, reduces hair tangling, and uses manageable cold-wash and air-dry care. The envelope opening does consume some usable insertion space, so a very bulky King pillow can be harder to load than the exterior dimensions suggest.
Secondary closure details are inconsistent, so this recommendation applies to the reviewed 20-by-37-inch envelope-style variant rather than every Brooklinen version.
Why It Works
- 37-inch length is purpose-built for a King pillow.
- Envelope construction avoids zipper hardware.
- The case has a smooth, substantial silk feel.
What To Keep In Mind
- The momme weight is not stated for the reviewed variant.
- The envelope flap reduces some usable insertion space.
How to Choose a Silk Pillowcase
Use momme as a density guide, not a score
Fishers Finery is 25 momme, Blissy is 22, and ZIMASILK and LILYSILK are 19. Denser silk can feel more substantial, but poor fit or weak stitching can still shorten the useful life of a heavier case.
Choose the closure you prefer to maintain
Envelope closures remove zipper hardware and the associated seam. Hidden zippers keep the pillow more fully enclosed but add a component that can fail. Neither style is automatically superior.
Match the case to pillow dimensions and loft
Standard, Queen, and King labels are not enough for a very plump pillow. Measure the insert and account for thickness. A tight silk case puts more tension on the seams and can flatten the pillow.
Keep beauty claims in perspective
A smooth silk surface creates less friction than rougher bedding and can feel more comfortable against hair. It should not be treated as a medical treatment for wrinkles, acne, or other skin conditions.
Plan the wash routine before buying
Cold water, gentle handling, mesh bags where permitted, and air or line drying recur across the care guidance. High dryer heat is the clearest avoidable risk because it can dull silk and stress delicate seams.
Frequently Asked Questions
What is the best silk pillowcase in this guide?
Fishers Finery is the strongest all-around pick because it combines the highest stated density at 25 momme with Grade 6A mulberry silk on both sides and an envelope-style closure without zipper hardware.
Is 25 momme better than 19 momme?
It is denser and more substantial, but not automatically better for every sleeper. Nineteen-momme silk is lighter, while closure quality, fit, and care still affect durability.
What does 22 momme mean?
Momme is a traditional measurement of silk fabric weight. A 22-momme case such as Blissy sits between the lighter 19-momme options and the denser 25-momme Fishers Finery case.
Is real silk different from polyester satin?
Yes. Silk is a fiber, while satin describes a smooth weave or finish and is often made from polyester. Both can reduce friction, but they differ in material, feel, and care.
Is a zipper or envelope better for a silk pillowcase?
A zipper keeps the pillow contained but adds hardware and a seam that can wear. An envelope avoids hardware but uses some interior length and can be looser on the insert.
Can silk pillowcases go in the dryer?
Do not assume so. Fishers Finery silk can lose luster after dryer use. Follow the exact sewn-in care label and favor air or line drying when required.
Do silk pillowcases sleep cool?
Silk has a cool, smooth surface, but cooling is not universal. Room temperature, pillow fill, and the sleeper's own heat output matter too.
How long should a silk pillowcase last?
There is no single lifespan. Repeated washing, pillow fit, momme weight, closure construction, and drying method all matter. Inspect zipper seams, edges, and thinning fabric during routine laundering.
