Momme [mom-ee] is a Japanese word used as a unit of weight measurement for real silk. Momme, often abbreviated as mm, is defined as the weight in pounds of a piece of fabric sized 45 inches x 100 yards. That is an incredibly long piece of fabric -- about the length of a football field! To put it terms closer to the size of sheets: one momme equates to about 4.340 grams per square meter. Eight momme fabric weighs about 1 ounce per square yard or 35 grams per square meter.
The higher the momme, the heavier and denser the weave will be. During the process of silk production, the silk factory will adjust the density and yarn count of the silk thread to control the weight -- or momme -- of the fabric. With 30 momme charmeuse pillowcase, for example, the weft and warp of the silk fibers are woven closer together than they would be for a 19 momme charmeuse pillowcase. Higher momme silk fabrics are also made with thicker yarn. In this way, momme is similar to thread count, which is commonly used to measure the weave of cotton sheets.
At Mulberry Park Silks, all of our products are made of the highest Grade 6A Mulberry silk.
Which Momme is Best for Me?
Choosing the right momme comes down to how you sleep, how often you’ll use your sheets, and the feel you prefer—lighter and airy or more substantial and indulgent. All momme options offer the same 100% pure Grade 6A mulberry silk quality; the difference is in weight, density, and overall sleep experience.
- Choose 19 Momme if you love a lighter, breathable feel and want an elegant introduction to silk bedding—especially if you tend to sleep warm.
- Choose 22 Momme if you want the best all-around option. This medium-weight silk strikes a beautiful balance between durability, softness, and everyday luxury, making it our most popular choice.
- Choose 30 Momme if you’re seeking the most substantial, indulgent silk experience. With a denser weave and richer hand feel, it’s ideal for those who want maximum longevity and a truly elevated sleep environment.
No matter which momme you choose, you’ll enjoy the signature smoothness, drape, and beauty benefits that make Mulberry Park Silks bedding an essential part of a self-care-focused sleep routine.
