A good silk pillowcase should feel smooth, hold the pillow securely, and fit the way you actually do laundry. The wrong size can pull tight at the seams, while a zipper or envelope closure may matter more than a small difference in silk weight.
These five picks use mulberry silk on both sides and range from 19 to 25 momme where a weight is given. If you are still deciding whether silk is the right material, the main pillowcase roundup compares it with cotton, satin, and other everyday options.

What Matters Most When Choosing Silk
Momme measures the weight of silk fabric. A higher number generally means a denser fabric, but weight alone does not decide comfort or durability. Stitching, fit, closure, and care all affect how well the case holds up. The guide to silk pillowcase quality explains why fiber grade and construction matter alongside momme.
Closure is the next practical choice. A hidden zipper keeps the pillow contained and gives the case a close fit. An envelope avoids zipper hardware and is simpler if you shift positions often. Silk can also wrinkle, show water marks, or lose sheen when exposed to heat, which is part of the downside of silk pillowcases.
Keep expectations realistic about beauty and health claims. A smooth surface creates less drag than a rough fabric, but a pillowcase is still bedding rather than a treatment.
Our Five Picks
1 / 5
Fishers Finery 25 Momme Silk Pillowcase
Material
100% Grade 6A mulberry silk on both sides
Silk weight
25 momme
Size
Queen, 20 x 30 in
Closure
Offset envelope flap
Fishers Finery uses a dense 25-momme mulberry silk fabric on both sides of its queen case. The 20-by-30-inch shape has a side opening that sits slightly off center, plus an oversized envelope flap that keeps the pillow inside. This gives you secure coverage without a zipper near your face.
The case feels well made and more substantial than many lighter silk options. Its envelope design was a clear plus for shoppers who did not want zipper hardware. Heat is the main caution: one case lost its luster after going through the dryer, so this is a better match for someone willing to air dry delicate bedding.
Why It Works
- A 25-momme fabric gives this case the densest stated silk in the group.
- Silk covers both sides rather than only the sleeping surface.
- The deep envelope flap keeps a queen pillow contained without hardware.
What To Keep In Mind
- Dryer heat can dull the smooth finish.
- The queen size is too loose for some standard pillows.
2 / 5
ZIMASILK 19 Momme Silk Pillowcase
Material
100% Grade 6A mulberry silk on both sides
Silk weight
19 momme
Size
Queen, 20 x 30 in
Closure
Hidden zipper
ZIMASILK pairs 19-momme mulberry silk with a hidden zipper and a 20-by-30-inch queen fit. Silk covers both sides, and the range includes more than 35 colors. The lighter fabric is smooth and breathable without the denser feel of a 22- or 25-momme case.
Softness, a cool feel, and a secure queen-pillow fit are the main strengths. Wrinkling and fit are less consistent. One case came out of a delicate wash very wrinkled and felt too tight on the pillow, while another fit a queen pillow well and washed cleanly when hung to dry.
Why It Works
- More than 35 shades make it easier to match existing bedding.
- A hidden zipper prevents the pillow from sliding out.
- Double-sided silk gives the case the same feel after flipping.
What To Keep In Mind
- The 19-momme fabric is lighter than the Fishers Finery and Blissy options.
- Air drying may still leave visible wrinkles.
3 / 5
LILYSILK 19 Momme Silk Pillowcase
Material
100% Grade 6A mulberry silk on both sides
Silk weight
19 momme
Size
Standard, 20 x 26 in
Closure
Hidden YKK zipper
LILYSILK is built for a standard 20-by-26-inch pillow and uses 19-momme mulberry silk on both faces. A concealed YKK zipper closes the open end, giving the case a clean edge and keeping the pillow from moving out overnight. This is the most specific zipper construction in the shortlist.
The silk feels soft, cool, and comfortable, and the standard fit works well when the pillow matches the stated dimensions. Zipper-area stitching is the weak point. Some cases held up through mesh-bag washing and line drying, while others ripped at or near the zipper seam much earlier than expected.
Why It Works
- A YKK zipper gives the closure a clear hardware specification.
- The 20-by-26-inch dimensions match a standard bed pillow.
- Silk on both sides keeps the feel consistent.
What To Keep In Mind
- Inspect the zipper seam before and after washing.
- A queen pillow will not fit the standard-size case correctly.
4 / 5
Blissy 22 Momme Silk Pillowcase
Material
100% Grade 6A mulberry silk
Silk weight
22 momme
Size
Standard, 20 x 26 in
Available fits
Standard, queen, and king
If skin claims are driving your purchase, read the practical discussion of dermatologists and silk pillowcases before paying more for marketing language.
Blissy uses 22-momme Grade 6A mulberry silk, placing it between the lighter 19-momme cases and the denser Fishers Finery. The prepared white variant is a 20-by-26-inch standard case, while the line also includes queen and king fits. The smooth, low-drag surface is the main reason to choose it over ordinary woven fabric.
The case feels soft and cool, and its colors make it a popular gift choice. Value is more personal. Some shoppers noticed a clear improvement over satin, while others felt little difference. Packaging condition also varied by color, so inspect the case and box when it arrives.
Why It Works
- A stated 22 momme offers more fabric weight than 19-momme options.
- Standard, queen, and king sizes cover common pillow formats.
- The smooth surface creates less drag than a rough woven case.
What To Keep In Mind
- Not everyone notices a major difference from good satin.
- Confirm the selected size before ordering because variants share the product family.
5 / 5
Brooklinen Mulberry Silk Pillowcase
Material
100% mulberry silk
Size
King, 20 x 37 in
Closure
Envelope
Care
Cold machine wash, lay flat to dry
Brooklinen is the only prepared king case in this group. It measures 20 by 37 inches and uses an envelope closure, so there is no zipper to press against the pillow or catch during washing. The mulberry silk is machine washable in cold water and should be laid flat to dry.
Its smooth surface feels soft without being excessively slippery, and the envelope design is easy to live with. Cases air dried in a few hours without needing ironing when smoothed first. The main unknown is fabric density because a momme weight is not provided, and some shoppers found it less silky than another well-known option.
Why It Works
- The 37-inch length fits a king pillow.
- An envelope flap holds the pillow without zipper hardware.
- Cold machine washing makes routine care less fussy.
What To Keep In Mind
- No momme weight is given for direct density comparison.
- Lay-flat drying needs more space than tumble drying.
Buying Guidance
Match the case to the pillow
Measure the pillow rather than relying only on the bed size. Standard cases here measure 20 by 26 inches, queen cases measure 20 by 30, and the Brooklinen king measures 20 by 37. A tight silk case stresses seams and changes loft, while an oversized case can bunch around the opening.
Choose zipper or envelope
Pick a hidden zipper when you want the pillow fully enclosed and do not mind checking the seam. Choose an envelope when you want less hardware and easier handling. Brooklinen and Fishers Finery use envelope designs, while ZIMASILK and LILYSILK use hidden zippers.
Compare weight without ignoring construction
Fishers Finery has the highest stated weight at 25 momme, followed by Blissy at 22. ZIMASILK and LILYSILK are 19 momme. Brooklinen does not state a comparable number. The separate look at Blissy versus other silk cases helps put brand and fabric weight in context.
Plan a gentle laundry routine
Cold water and air drying are the safest common habits across these cases. Use a mesh bag when the care label permits it, close zippers, and keep rough hooks away from the fabric. If drying space is limited, the guide to air drying bedding indoors can help you plan enough airflow.
Frequently Asked Questions
Which silk pillowcase is best overall?
Fishers Finery is the strongest all-around choice because it combines dense 25-momme silk, queen dimensions, double-sided construction, and a secure envelope without zipper hardware.
Is 19, 22, or 25 momme better?
Higher momme usually feels denser and more substantial. Nineteen momme is lighter, 22 is a useful middle point, and 25 provides the most fabric weight here. Stitching and care still affect durability.
Is a silk pillowcase better than satin?
Silk is a natural protein fiber, while satin describes a smooth weave and is often made from polyester. Both can feel slick, but silk usually costs more and needs gentler care.
Do silk pillowcases stay cool all night?
They feel smooth and breathable, but no pillowcase stays cold in every room. Pillow fill, room temperature, and body heat still affect comfort. For other fabric approaches, compare the best cooling pillowcases.
Can I put a silk pillowcase in the dryer?
Do not assume that you can. Dryer heat dulled one Fishers Finery case, and several options call for flat or line drying. Follow the sewn-in care label for your exact case.
How often should I wash a silk pillowcase?
Wash it often enough to remove skin oils and hair products, usually with the rest of your pillowcase rotation. Gentle detergent, cold water, and proper drying matter more than forcing a rigid schedule.
Is an envelope closure better than a zipper?
An envelope has no hardware and is less likely to create a pressure point. A zipper holds the pillow more securely but adds a seam that can wear. Choose the style that fits how much your pillow shifts.
