Waking up with tangled hair, creased skin, or a hot, sweaty pillow is a sign your bedding is fighting you, not helping you. A genuine mulberry silk pillowcase changes that equation by replacing friction with a gliding surface that lets your hair and skin retain moisture through the night.
I’m Mohammad — the founder and writer behind ProteinJug. Over the past several years I’ve analyzed hundreds of bedding SKUs, cross-referencing momme weight, filament grade, weave density, and real-world wash durability to separate authentic mulberry silk from polyester impostors.
After sifting through thousands of verified customer reviews and spec sheets, I’ve narrowed the market to the seven pure mulberry options that actually deliver on their promises. This is the definitive guide to the best silk pillowcases for hair, skin, and true sleep comfort.
How To Choose The Best Silk Pillowcases
Not all silk is created equal. Terms like “mulberry silk,” “momme,” and “Grade 6A” are often used interchangeably, but they define very different levels of quality. Understanding these three core specs will save you from buying a glorified polyester satin case.
Momme Weight: The Density That Defines Durability
Momme (mm) measures the weight of the silk fabric — higher numbers mean a denser, heavier, and more durable weave. Entry-level silk pillowcases hover around 19 momme, which is soft but thinner and prone to wear. Mid-range options at 22 momme offer a noticeably better balance of softness and longevity. Premium picks at 25 to 30 momme feel plush, almost velvety, and resist pilling far longer. For daily use, 22 momme is the sweet spot; if you want a truly luxurious feel, step up to 25 or 30 momme.
Filament Grade and Length: The 6A Standard
Mulberry silk is graded from A to 6A, with 6A being the highest. A 6A rating means the silk filaments are long, continuous, and free of impurities, resulting in a smoother surface that won’t snag or pill. Lower grades use shorter, broken fibers that require spinning into a less uniform thread. Always look for a listed “Grade 6A” on the product page — any pillowcase that omits this spec is almost certainly using lower-grade silk.
Closure Type: Zipper vs. Envelope
A hidden zipper keeps the pillowcase snug and prevents the pillow from shifting during the night. The downside is that some users find the zipper uncomfortable if it presses against the face. An envelope closure (fold-over design) is completely smooth on both sides, easier to remove for washing, and ideal for those with sensitive skin. However, envelope cases can sometimes slip off thinner pillows. Choose based on whether you prioritize stability or a completely seam-free surface.

In‑Depth Reviews
1. ZIMASILK 22 Momme Silk Pillowcase
The ZIMASILK hits the 22-momme sweet spot that most mid-range options miss. At this density, the fabric has enough heft to feel substantial without being stiff, and the Grade 6A long-filament construction gives it that signature cool-to-the-touch glide. The hidden zipper keeps the pillow locked in place all night — no slipping, no bunching.
Multiple reviewers with long, thick hair report that morning knots virtually disappeared after switching to this case. The OEKO-TEX certification adds peace of mind for anyone with sensitive skin or allergies. After several months of weekly machine washing on gentle cycle, the material holds its shape and color without noticeable pilling.
This is the benchmark for a single premium pillowcase. You get the density that genuinely reduces friction, a closure that works, and a price that undercuts comparable boutique brands. If you only buy one silk pillowcase, make it this one.
Why it’s great
- 22 momme provides ideal thickness and durability
- Hidden zipper prevents shifting without scratching
- OEKO-TEX certified for sensitive skin
Good to know
- Single pack only — one per pillow
- Need to wash on delicate cycle to preserve sheen
2. Bella Coterie 30 Momme Luxury Silk Pillowcase
At 30 momme, the Bella Coterie is in a different weight class. That extra density translates into a fabric that feels almost like a thick, buttery charmeuse — it drapes heavily and resists creasing far better than any 19-momme alternative. The Grade 6A mulberry silk is the real deal, and the zipper is discreet enough that most users won’t notice it while sleeping.
Reviewers consistently mention that their skin looks less creased in the morning and that their hair tangles significantly less. The tighter weave also means the case stays cool longer into the night compared to lighter silk options. It does run slightly larger than standard pillows, which some users find loose, but the zipper compensates by holding the pillow firmly.
If you are willing to invest in the thickest, most durable silk construction available at this price point, the Bella Coterie delivers a truly plush experience that cheaper cases cannot match.
Why it’s great
- 30 momme is the densest weave in this guide
- Exceptional temperature regulation — stays cool longer
- Hidden zipper keeps pillow securely in place
Good to know
- Single pack; premium tier pricing
- Runs slightly loose on standard pillows
3. Blissy Toddler Silk Pillowcase
Blissy’s toddler-specific pillowcase uses the same 22-momme, Grade 6A construction as their adult line, scaled down to 18 by 13 inches. The envelope closure is a smart choice for kids — no zipper to scratch a sleeping face, and the fold-over design makes it easy for parents to swap cases mid-week. The fabric is OEKO-TEX certified and completely hypoallergenic, addressing common concerns about dust mites and allergens in children’s bedding.
Parents report that their kids’ hair tangles noticeably less and that skin irritation from rough cotton cases disappeared after switching. The machine-washable care routine holds up well, though some users note that the case requires a gentle cycle and air drying to maintain its smoothness.
For families with young children who have sensitive skin or easily tangled hair, this is a purpose-built solution that eliminates the guesswork of buying a standard pillowcase that might not fit properly.
Why it’s great
- Designed specifically for toddler-size pillows
- Envelope closure is safe and scratch-free
- Hypoallergenic and OEKO-TEX certified
Good to know
- Single pack; priced at premium tier
- Requires delicate washing and air drying
4. ALASKA BEAR 22 Momme Envelope Silk Pillowcase
The ALASKA BEAR case is built for people who want the benefits of 22-momme mulberry silk but cannot stand sleeping on a zipper. The long overlap envelope closure creates a smooth, uninterrupted surface on both sides, which is excellent for side sleepers who press their face into the pillow. The 6A long-fiber silk has a noticeable coolness and a subtle sheen that looks refined on the bed.
Reviewers with 2b curls and sensitive skin specifically praise this case for reducing morning frizz and preventing the dry, irritated feeling they got from cotton. The included silk scrunchie is a nice bonus, but the real draw is the no-zipper construction that won’t compress or scratch. Hand washing is recommended, though several users confirm it holds up well on a gentle machine cycle in a mesh bag.
If you prioritize a completely seam-free feel and prefer not to deal with zippers, this is the best-executed envelope-style option in the mid-range tier.
Why it’s great
- No zipper — completely smooth on both sides
- 22 momme with Grade 6A long-fiber silk
- Comes with a silk scrunchie
Good to know
- Envelope can slip off thinner pillows
- Hand washing recommended for longevity
5. ZIMASILK 19 Momme 2-Pack Silk Pillowcase Set
This two-pack from ZIMASILK uses 19-momme Grade 6A mulberry silk on both sides, making it a practical choice for couples or for those who want a spare case in the wash rotation. The fabric is lighter and less dense than the 22-momme version, but it still offers a genuine silk feel that satin imitations cannot replicate. The hidden zipper is the same reliable design found on their premium single.
Reviewers with curly hair note that this case still reduces frizz and bed head, though the thinner 19-momme weave means it may show wear sooner than a heavier option. The set comes in over 35 colors, which is useful if you are trying to coordinate with existing bedding. The 180-day warranty covers any manufacturing defects, adding a safety net for first-time silk buyers.
If you need two cases for a reasonable outlay and are comfortable with the lighter 19-momme weight, this set delivers genuine mulberry silk construction at a low per-unit cost.
Why it’s great
- Two premium-grade silk cases in one purchase
- Hidden zipper keeps pillows secure
- Extensive color selection (35+ options)
Good to know
- 19 momme is less durable than 22 momme
- Thinner fabric may be less cool over time
6. THXSILK Set of 2 Pure Mulberry Silk Pillowcases
THXSILK offers a two-pack of Grade 6A+ mulberry silk at an entry-level price point. The hidden zipper is neatly concealed and helps the case stay tight on the pillow, which is a common complaint with cheaper envelope designs. The fabric is smooth and antistatic, and several users with dry hair report less breakage after switching from cotton.
The primary caveat here is consistency. A few reviewers have noted that the momme weight is not explicitly listed on the packaging, and some speculate it is closer to 19 momme than the higher density found in dedicated 22-momme brands. That still qualifies as real silk, but buyers expecting a thick, plush weave may be disappointed. The set washes well in a mesh bag on gentle cycle, with no reported dye bleeding or fraying after multiple loads.
For budget-conscious shoppers who want two genuine silk cases without paying for boutique branding, this set gets the job done. Just know you are trading some denseness for the lower cost per unit.
Why it’s great
- Two silk cases at a low per-unit price
- Hidden zipper prevents pillow from slipping
- Washes well; no dye bleeding reported
Good to know
- Momme weight not explicitly listed on packaging
- Lighter weave may not suit those seeking heavy silk
7. Bare Home 19 Momme Mulberry Silk Pillowcase
Bare Home’s entry-level case uses 19-momme Grade 6A mulberry silk with an envelope closure. The fabric is lightweight and breathable, which makes it a good introduction to silk for users who have never tried one before. The envelope design is straightforward — no zipper to snag or scratch — and the pillow slides in and out easily for washing.
Customer feedback consistently points to a noticeable reduction in hair tangling and a cooler sleep surface compared to cotton. A few users who own both this case and a 22-momme Blissy case say the Bare Home feels noticeably thinner but still outperforms satin alternatives. The 30-night guarantee lets you test it risk-free, which is helpful if you are unsure whether silk bedding is right for you.
For a first purchase or a spare case, the Bare Home is a solid, no-frills option. Just be aware that the 19-momme weave will not have the same plush feel or longevity as a 22-momme alternative.
Why it’s great
- Genuine 19-momme Grade 6A mulberry silk
- Envelope closure is safe and easy to use
- 30-night guarantee for first-time buyers
Good to know
- Thinner weave; less durable than 22-momme options
- Single pack only
