Enjoy the luxury, strength, thermal capabilities and hypoallergenic properties of our lightweight pure silk covered and pure silk filled duvets. Your body recovers and regenerates while you sleep so why not give yourself the best sleeping experience? Body temperature drops as you enter into deep sleep and as the thermal capability of silk works to allow air to flow more freely around your body, trapping heat and dissipating sweat, this will giving you a more comfortable and refreshing sleep. People with skin conditions feel the benefit too, as the light, smooth silk soothes irritated and itchy skin. PATRA duvets do not include cotton content, as do many of our competitors. The amino acid properties of our pure silk fibres act to repel house mites so asthma sufferers find they can breathe more freely. PATRA have been in business for over 45 years and this is just another best selling item in our bedding range developed with the help of feedback from our loyal customers. Cool in summer, cosy in winter and surprisingly light in weight. The filling is constructed of long silk fibres. Bundles of filament strands are stretched together into thin gossamer layers then wadded together in layers and covered with pure silk habotai giving the excellent thermal properties of our duvets.
