The Luxeport Mulberry Silk light duvet is perfect for summer nights and mild temperatures. In the winter the large silk fibres reduce thermo-conductivity (heat loss) from the body, but in the summer the silk fleece sheds surplus heat by wicking away moisture from your body, keeping you cool and comfortable. This is the ultimate in luxury bedding. | Luxeport 300 Thread Count Premium Light Silk Duvet - King - White
