When choosing a silk pillowcase, you may come across terms such as 22 momme or 25 momme.

But what do these numbers actually mean?

Momme (pronounced “mom-ee”) is a traditional measurement of the weight of silk fabric. The higher the momme, the more silk is used within a given area of fabric.

As a result, 25 momme silk is heavier and more substantial than 22 momme silk—but both offer a beautifully smooth and luxurious feel.

22 Momme Silk

22 momme is a popular choice for a luxurious yet lightweight silk pillowcase.

It offers the smooth, soft feel associated with silk while remaining light and comfortable against the skin. For everyday use, 22 momme provides a beautiful balance of softness, quality and practicality.

25 Momme Silk

25 momme takes that sense of luxury a little further.

With more silk used in the fabric, it has a fuller, more substantial feel. Rich, smooth and beautifully indulgent, it is often chosen by those seeking a more premium silk experience.

So, Which One Should You Choose?

Neither is simply “better”—each offers a slightly different experience.

22 Momme
Light, smooth and luxurious, making it an excellent choice for everyday use.

25 Momme
Fuller, more substantial and indulgent, ideal for those who prefer a richer silk feel.

Ultimately, the choice comes down to personal preference.

A Little More Silk, a Different Feel

The difference between 22 and 25 momme may sound small, but it creates a noticeable difference in the weight and feel of the fabric.

At Alba Weave, we offer both because we believe luxury is personal. Some prefer the lighter elegance of 22 momme, while others appreciate the fuller, more substantial feel of 25 momme.

Whichever you choose, the beauty of silk lies in its simplicity—smooth against the skin, naturally elegant and able to make an everyday ritual feel a little more special.
