by Zoe Doyle | January 20, 2026 | 3 min read

Silk pillowcases come in a variety of momme weights. Momme is a weight measurement for silk that is similar to thread count. This article explains how to choose the best momme weight silk pillowcase for your needs and budget.

Key Takeaways

  • Knowing About Silk Momme Weight is Essential for Choosing the Best Silk Pillowcase.When shopping for a 100% mulberry silk pillowcase, silk momme weight is the most important factor to understand. At Mulberry Park Silks, momme ranges from 19 to 30 — and the higher the momme count, the heavier, denser, and more durable the pure silk. Whether you're new to silk bed linen or upgrading your sleep routine, knowing your momme helps you find the best silk pillowcase for your needs and budget.

  • All Momme Weights Deliver the Benefits of 100% Mulberry Silk.Regardless of which momme weight you choose, every Mulberry Park Silks silk product is made from 100% mulberry silk, Grade 6A, and Oeko-Tex® Standard 100 certified. That means every pillowcase — from 19 to 30 momme — supports better sleep, reduces hair breakage, retains moisture, and minimizes friction on skin. Unlike a satin pillowcase, pure silk delivers these benefits naturally.

  • Higher Momme Means More Silk, Greater Durability, and Ultimate Luxury.The 30 momme pillowcase contains 58% more silk than the 19 momme option, with the thickest silk thread, tightest weave, and longest-lasting durability. For those who want the finest silk bed sheets and silk bedding experience, 30 momme is the ultimate indulgence — while the 22 momme remains the most popular all-around choice for quality and value.

A Mulberry Park Silks pillowcase helps prevent tangles, bed head, and hair breakage; allows hair and skin to retain moisture; and minimizes sleep wrinkles (it's friction-free and won't tug on delicate facial skin). Our momme silk is also naturally temperature regulating, hypoallergenic, non-irritating, and resistant to mold and dust mites. There are so many great reasons to sleep on our silk pillowcases.

You can also feel good about any silk pillowcase you buy from Mulberry Park. All of our silk charmeuse pillowcases are made from 100 percent pure mulberry silk, Grade 6A (the highest in the marketplace), and Oeko-Tex® Standard 100 certified to be free of any harmful substances.

Understanding Silk Pillowcase Weight (momme)

At Mulberry Park Silks, our silk pillowcases come in three momme weights ranging from 19 to 30 momme;  momme (mm) is a unit of measurement that denotes the weight of silk. As momme increases, silk is heavier, denser in weave, and more costly. Higher momme silk is also made with thicker silk fibers.

Comparing Silk Pillowcase Momme Weights

Learning a bit about the different momme silk weights can help you identify the silk pillowcase that works best for your personal preferences and budget:

19 Momme Silk Pillowcase Weight

This is a lovely silk and our most affordable option. With a competitive price point, our 19 momme pillowcases are an ideal entry-level purchase for anyone new to silk who wants to try it out. Our 19 momme natural silk pillowcases are luxurious and beneficial to hair and skin; however, they have less silk than those of higher momme weight, and so are a bit more delicate. Available in six color options (see chart below).

22 Momme Silk Pillowcase Weight

This silk pillowcase is more expensive, but still available at an affordable price point. Our 22 momme silk pillowcases are the same weight as our most popular sheet set. They contain 16 percent more silk than the 19 momme pillowcase and offer excellent durability in a tight weave with regular silk strands. Available in seven color options that coordinate with our 22 momme flat and silk fitted sheets.

30 Momme Silk Pillowcase Weight

The 30 momme silk pillowcases are the ultimate in luxury and indulgence. With 58 percent more silk than a 19 momme pillowcase, they are our most expensive pillowcase and well worth the investment. They are exceptionally durable, with the highest density of silk; the tightest weave; and the thickest silk strands.

How to Care for Your Momme Silk Pillowcase

All Mulberry Park Silks pillowcases--no matter the momme weight--are easy to care for. You can wash your silk pillowcase by hand or machine following these simple guidelines. If you are washing by machine, we recommend turning your pillowcase inside out and placing it in a fine mesh laundry bag to protect it during the wash cycle. Use cool water and a delicate or silk cycle with a detergent specially made for silk like Heritage Park Luxury Silk, Wool, and Cashmere Detergent. This pH neutral formula will clean your silk while protecting the integrity of the fabric. Hang your silk pillowcase to dry indoors or outside away from direct sunlight which can fade silk fabric. Ironing your silk pillowcase is not necessary, but if you choose to iron silk, use the lowest heat setting and follow these directions.

Frequently Asked Questions

Momme is a weight measurement used specifically for silk that tells you how much silk is in the fabric. A higher momme count means more silk thread, a denser weave, and a heavier, more durable silk product. For silk bed sheets, silk pillowcases, and other silk bed linen, momme is the single most reliable indicator of quality and longevity.

While both momme and thread count relate to fabric density, they are not the same thing. Thread count simply measures how many threads are woven per square inch; it's a density measurement used primarily for cotton bed sheets and other woven fabrics. Momme, on the other hand, is a weight measurement unique to silk that reflects not just density but also the amount of silk thread used, the length of the silk strands, and the overall richness of the weave. A higher momme means more silk fiber, longer strands, and a heavier, more substantial fabric which makes it a far more meaningful measure of quality for 100% mulberry silk than thread count alone.

Yes. A satin pillowcase is typically made from synthetic materials like polyester and only mimics the look of silk. A 100% mulberry silk pillowcase delivers genuine benefits for sleep, including temperature regulation, moisture retention for hair and skin, and a friction-free surface that reduces sleep wrinkles and hair breakage. Pure silk is also naturally hypoallergenic, which satin cannot replicate.

It depends on your budget and lifestyle. The 19 momme is a beautiful, affordable entry point into pure silk — ideal for first-time silk buyers. The 22 momme is the most popular choice, offering excellent durability and value and coordinating with Mulberry Park's silk bed sheets. The 30 momme is the ultimate luxury silk product — the heaviest, densest, and most indulgent option available. All three are 100% mulberry silk and machine washable.

Absolutely — pairing a silk sleep mask with your silk pillowcase is one of the best ways to maximize the benefits of silk bedding. Both are made from 100% mulberry silk, so your skin enjoys the same friction-free, moisture-retaining, hypoallergenic surface all night long, creating a complete luxury sleep environment from head to pillow.
