Our California King silk sheets are crafted from 100% pure mulberry silk in a charmeuse weave. They come in two different momme weights: 22, and 30. Momme is a measurement of silk fabric that is similar to thread count; higher momme silk is more densely woven and the silk fibers are thicker.

Higher momme sheets have proportionately more silk than lower momme sheets of the same size. A 30 momme sheet has approximately 35% more silk than a 22 momme sheet of the same size. A higher momme count means more silk, heavier fabric, and more costly sheets.

What temperature sleeper are you?

• If you are a hot sleeper, we recommend our signature 22 momme weight sheets which are breathable and comfortable.
• If you are a cold sleeper we recommend either our 22 momme weight sheets (a popular mid-weight option) or our 30 momme sheets (a heavier weight for the ultimate in warmth and luxury).
