Our 100% Dupioni Mulberry Silk Duvet Insert is filled with top grade dupioni long-strand mulberry silk, and encased in 100% GOTS certified organic cotton. The silk duvet is soft, fluffy, lightweight yet warm. Both fills and shell are OEKO-TEX certified for not containing any harmful chemicals. 

• Fills: 100% Double Cocoon (also known as Dupioni or 7A) Long Strand Mulberry Silk - the most premium grade of silk. 
• Shell: GOTS certified organic cotton, 300 thread count, sateen weave with a natural warm white hue and lustrous sheen.
• Design: A tack stitch pattern is employed to enhance fill stability while preserving the duvet's smooth and fluffy texture. The long fibers of genuine long-strand silk naturally adhere to the shell, making the use of large-scale stitching patterns, like box construction, unnecessary and potentially detrimental to the overall texture and feel.
• Three loops on each duvet side for secure cover attachment.
• Handmade by expert artisans in China with decades of experience. The fillings are hand-stretched from silk cocoons to ensure even silk fibre distribution. 

• Duvet cover is strongly recommended to be used together.
• Sun-curing recommended to remove moisture and dirt.
• Dry clean at the Professional's. 
• Spot clean if necessary.
