Details

Color: Warm White

Choose from Three Weights: Light, All-Season, and Heavy

Available in Three Sizes: Twin/Twin XL, Full/Queen, and King/Cal-King

Premium Silk Fill: Filled with 100% double-cocoon long-strand mulberry silk, widely recognized as the smoothest and most durable grade of silk available for bedding.

Organic Cotton Shell: Encased in a 300 thread count sateen weave made from GOTS-certified organic cotton, featuring a natural warm white hue with a subtle, luminous glow.

Artisan Craftsmanship: Handmade by master artisans with decades of experience, where each silk fill is meticulously hand-stretched from cocoons to ensure a smooth, even distribution of fibers.

Tack Stitch Design: Because long-strand silk naturally and firmly adheres to the cotton shell, traditional heavy box stitching is unnecessary. A refined tack stitch technique reinforces the insert without ever compromising the natural texture of the silk filling.

Secure Cover Attachment: Equipped with three loops on each side of the duvet so you can easily tie it securely inside a cover.

Transparent Quality: Features a hidden 12 cm zipper seam along the edge, allowing you to easily inspect the authentic long-strand silk fill for total peace of mind.

Eco-Friendly Packaging: Arrives in a reusable and recyclable non-woven fabric storage bag.
