What Momme Silk is the Best for Pillowcases? Fabric Weight Explained
Key Takeaways
-
Momme is silk's fabric weight, and 19 to 30 momme is the usable range for pillowcases.
-
At 19 and 22 momme, pillowcases feel soft but lose their smooth finish faster under daily washing and friction.
-
Mayfairsilk settles the question by building every pillowcase at a full 25 momme, while most silk brands stop at 22; that extra weight keeps the weave dense enough to glide against hair and skin through years of washes.
-
A 25 momme pillowcase holds about 115 grams of silk, roughly 64% more than a 19 momme case, which is what gives it the weight, sheen, and staying power lower weights can't match.
-
Mayfairsilk makes every pillowcase from Grade 6A Mulberry silk at a full 25 momme, with tight finishing and a matte sheen that holds up night after night.
The Best Momme for Silk Pillowcases: What You Need to Know
25 momme is the best silk weight for pillowcases, with 22 momme as the strong runner-up and 19 momme as the lightweight starter option. At 25 momme, the weave is dense enough to keep its sheen and slip through years of nightly use; 22 momme gives you most of that for less; 19 momme is soft and breathable but wears thinner under daily washing. Which one fits depends on how often you sleep on it, how warm a room you sleep in, and how long you want it to last.
Silk pillowcases have crossed from beauty-product novelty to a regular bedding category, and momme has become the spec people actually compare. Get the weight right and the rest of the experience falls into place.
If you're picking your first silk pillowcase or upgrading from a thinner one, the breakdown below covers what each weight feels like, how long it lasts, and where Mayfairsilk's 25 momme fits in.

What Should You Consider in Choosing the Right Silk Pillowcase Momme Weight?
-
Budget: If you’re just starting with silk, 19 momme is an affordable starting point. If you’re ready to splurge, 25–30 momme delivers that premium feel.
-
Durability Needs: For everyday use and regular washing, 22 momme or higher holds up best.
-
Climate and Comfort: 19 momme is light and breathable; great for warm weather or hot sleepers. Heavier weights feel warmer and more substantial.
-
Aesthetic Preferences: Higher momme silk has a rich, luminous sheen that has a high-end look.
-
Hair and Skin Benefits: All momme weights are kind to your hair and skin, but the heavier ones hold up longer, so you get those hair and skin benefits over time.
What Other Factors Affect Silk Pillowcase Quality?
Momme weight tells you a lot, but it isn't the only thing that shapes how a pillowcase performs. The type of silk, the weave, and the quality of the finishing all play a role. Getting these right separates a pillowcase that lasts from one that wears out in a season.
Mulberry silk is the gold standard. Its long, uniform fibres make it smoother, stronger, and naturally hypoallergenic compared to wild or blended silks. Charmeuse is the weave to look for, with a shiny face and a matte back that gives you the slip-and-slide surface silk is known for.
Finishing matters just as much as fabric. Clean stitching, careful dyeing, and tight seams are what keep a pillowcase looking sharp after dozens of washes.
25 is the ideal momme weight for silk pillowcases.
Why 25 Momme Wins for Pillowcases
A 25 momme silk pillowcase is built to hold up for years of nightly use, wash after wash.
If you want a silk pillowcase that holds its sheen and smoothness past the first few months, 25 momme is the answer. 22 momme is a sound mid-tier pick and 19 momme is a fair starting point, but 25 is where durability and the silk experience peak together.
That's exactly the spec Mayfairsilk builds to. Every pillowcase ships at a full 25 momme in Grade 6A Mulberry silk, with seams that hold up to nightly washes and the dense, even drape lighter weights can't reach. The first night tells you everything you need to know.

Frequently Asked Questions (FAQ)
How long does a 22 momme silk pillowcase typically last?
With good care, a 22 momme silk pillowcase can last 1–2 years of nightly use. That’s about 100–150 gentle washes before wear and tear starts to show.
Can I machine wash higher momme silk pillowcases?
You can, as long as you do it carefully. Use a mesh laundry bag, a delicate cycle with cold water, and a detergent made for silk. Avoid heat, fabric softeners, and bleach, and always air dry out of direct sunlight. Heavier momme silk holds up better than lighter weights, but it still needs good maintenance.
Why are 19-momme silk pillowcases so much cheaper?
They use less silk, around 14% less than 22 momme and nearly 37% less than 30 momme, so they cost less to produce. That makes them a more budget-friendly entry point into silk, but with trade-offs in durability.
Will a higher momme silk pillowcase help with my hair and skin more?
Yes, but only slightly. All silk pillowcases reduce friction and retain moisture, which is great for hair and skin. Heavier momme silk has a denser weave that stays smoother longer, giving a small boost in those benefits. But the biggest difference is when you switch from cotton to silk; going from 22 to 30 momme is more of a luxury upgrade than a must for most people.
Are Mayfairsilk pillowcases suitable for sensitive skin and allergies?
Absolutely! All Mayfairsilk pillowcases are naturally hypoallergenic, antibacterial, and dust mite resistant, making them a gentle and safe choice for sensitive skin and allergy-prone sleepers.
