The Drowsy Midnight Blue Silk Pillowcase is a 22 momme silk pillowcase in midnight blue. Standard size: 75×50cm. Envelope closure. 100% machine washable. Silk is a protein fibre with a lower friction coefficient than cotton — the surface produces less friction against hair and skin during sleep compared to a standard cotton pillowcase. Sold individually.
Why you'll like it
- 22 momme silk — higher momme weight indicates a denser, heavier weave
- Standard size: 75×50cm — fits a standard UK pillow
- Envelope closure — no zip; keeps the pillow in place
- Lower-friction surface vs cotton — silk's protein fibre structure produces less friction against hair and skin during use
- 100% machine washable
- Midnight blue colourway
Designed as
The Drowsy pillowcase uses a 22 momme silk weave. Momme (mm) is the weight measurement for silk fabric — 22 momme is a heavier, denser weave than the standard 12–16 momme used in many silk accessories. The envelope closure secures the pillow without a zip. Silk is a natural protein fibre; its lower coefficient of friction compared to cotton produces less mechanical resistance against hair and skin during sleep. This is a material characteristic of silk fabric, not a therapeutic or medical claim. 100% machine washable.

What does 22 momme mean?
Momme (mm) is the traditional weight measurement for silk fabric, equivalent to the thread count concept used for cotton. It describes the weight of a 45×100 yard piece of silk in pounds. 22 momme indicates a heavier, denser silk weave — the fabric is thicker and more durable than the 12–16 momme range typically used in lower-cost silk accessories. Higher momme weight generally means greater durability and a richer hand-feel, though this varies by weave type.
How does silk differ from cotton as a pillowcase material?
Silk is a natural protein fibre with a smooth, low-friction surface. Its coefficient of friction against hair and skin is lower than that of cotton, which has a rougher surface texture due to the cellulose fibre structure. The practical effect is less mechanical resistance against hair and skin during sleep compared to a standard cotton pillowcase. This is a material property of the fabric and is not a medical or therapeutic claim.
How should I wash it?
The Drowsy Midnight Blue Silk Pillowcase is 100% machine washable. Refer to the care label on the product for the specific recommended wash cycle, temperature, and drying instructions.
