Experience personalized comfort with our standalone silk-filled core. Engineered to work flawlessly with KAILU duvet covers through a precision 1-to-1 tie system, it stays perfectly positioned without shifting. Built from hand-stretched mulberry silk using traditional methods, each layer is carefully stacked and stitched for consistent weight distribution and breathability. Pure natural fill that molds to your needs with no synthetics or cold spots. Use a single core for lighter coverage or layer two together for extra warmth.

100% long-strand mulberry silk fill
100% cotton sateen fabric casing
Allergy resistant / dust-mite free
Naturally temperature regulating
Supremely breathable
Includes 8+ ties to correspond with duvet cover
Hidden zipper closure

Twin: 66 in. x 86 in.
Queen: 86 in. x 86 in.
King: 94 in. x 104 in.

We recommend Emperor for a Cal-King bed, and Queen for a Full bed.

To maximize the effectiveness of silk filling, our duvets have been designed to “float.” If you prefer a draped style or wish to tuck it under your mattress, we recommend choosing the next size up.

Environmental Impact

KAILU highlights the use of raw silk, a natural and biodegradable fiber, valued for its purity and minimal processing. By working with silk in its more natural state, the brand emphasizes material integrity and a reduced reliance on synthetic alternatives.

Sourcing

The brand sources raw silk with careful attention to traditional sericulture practices in the Yangtze River Delta, a region historically known for silk production. This approach preserves the natural structure and performance of silk while honoring longstanding techniques passed down through generations.
