Made with over 150 layers of silk floss webbing, our Contessa Mulberry Silk Duvet is designed for all-seasons! This duvet provides the perfect degree of warmth while adding a little more weight on your body than our lighter Pearl Mulberry Silk Duvet. The luxuriously soft, 400 thread count cotton jacquard shell is box-stitched to secure the silk floss in place and ensure total comfort. All our silk duvets are made leveraging the traditional methods used for centuries in China. The result? An even fill and a beautiful, soft drape that contours the body. As one of the strongest natural fibers in the world, silk makes for an incredibly durable and long-lasting duvet. Plus, silk is naturally hypoallergenic and highly resistant to dust mites and bacteria. Finally, silk possesses exceptional temperature regulating properties - it keeps warm sleepers cool and cool sleepers warm! So a silk duvet is a great choice for those who share a bed, but prefer different sleeping temperatures.To learn more about our duvets, read our Duvet Guide!Have questions about this duvet or need helping finding your perfect fit?
