Understanding Silk Fabric Weights

Silk, a natural protein fiber spun by silkworms, is renowned for its softness and lustrous appearance. The weight of silk fabric is measured in momme, a Japanese unit of weight used to express the density of silk. A higher momme indicates a denser and more substantial fabric. Here’s a brief description of the different types of silk fabrics.

22 Momme Silk

22 momme silk is slightly lighter than 25 momme silk. It strikes a balance between durability and comfort. It is an ideal choice for those looking for a luxurious feel without the added weight.

23 Momme Silk

Falling between 22 momme and 25 momme silk, 23 momme silk provides a medium-weight option. It combines the best of both worlds, offering a comfortable feel and excellent durability, making it an excellent choice for a wide range of silk products.

25 Momme Silk

It is considered one of the heavier and more durable silk fabric options, 25 momme silk is often used for luxurious silk bedding and apparel. Its thickness lends it a luxurious feel, making it a popular choice for those seeking a richer texture.

30 Momme Silk

At the higher end of the silk fabric weight spectrum, 30 momme silk is the epitome of luxury. Its unparalleled durability and thickness make it a top-notch choice for long-lasting silk products, but it may be less suitable for those who prefer lighter fabrics.

Is silk more breathable than cotton?

Breathability is a crucial factor to consider, especially for bedding and sleepwear, as it directly impacts sleep quality. Silk and cotton have distinct characteristics that affect their breathability.

Cotton Breathability

Cotton, a natural plant-based fiber, is well-known for its breathability and moisture-wicking properties. It allows air to circulate freely, making it an excellent choice for hot and humid climates or for individuals who tend to sweat during the night.

Silk Breathability

Silk is also highly breathable, but its level of breathability depends on the momme weight of the fabric. Lighter momme silk, such as 22 momme or 23 momme, offers enhanced breathability, making it suitable for warm weather. The fabric allows air to flow, preventing overheating during sleep.

Conversely, heavier momme silk like 25 momme or 30 momme provides excellent insulation, making it a more suitable choice for cooler climates or colder seasons. The denser weave retains body heat, keeping you warm and cozy during chilly nights.


In conclusion, silk is indeed a breathable fabric, particularly when considering lighter momme weights like 22 momme and 23 momme. Its ability to regulate body temperature and provide a smooth surface for hair and skin health makes it a top choice for bedding and sleepwear.

While cotton also offers breathability, silk's unique properties make it a luxurious and practical option for a comfortable night's rest. Whether you prefer the medium-weight 23-momme silk or the heavier 30-momme silk, investing in silk pillowcases and silk sheets is sure to enhance your sleep experience and overall well-being.
