Pure silk is one of natures finest insulators, it holds heat near the body and quickly absorbs any excess moisture away from your body and into the air, regulating the temperature. This ability to breathe makes our Rockcloud duvets incredibly comfortable to sleep beneath, as they keep you wonderfully warm in winter and cool in the summer. Silk duvets are lightweight, soft and flexible and will conform to every contour of your body, as if wrapped in a soft and delicate cloud. Silk is naturally hypoallergenic and will repel mould and mildew. The dust-mite is unable to exist in silk, making it the best alternative for a peaceful, allergy free sleep to any other product available. This can be of positive benefit to eczema and asthma sufferers. The silk floss is made from the finest mulberry silk, which is farmed organically and traditionally made without the use of chemicals, ensuring that the silk is not compromised in any way, so that all users will enjoy the natural healthy benefits that silk provides. The silk is covered with a pure cotton cover. Mulberry silk is a natural protein fibre, made up of many amino acids, which the Chinese believe to be good for your skin and your general health. At Rockcloud we understand, that by helping people sleep better, it will improve their overall sense of well being. A Rockcloud silk duvet will give you many years of good service providing you follow our simple but essential care instructions. Silk does not break down and is not eaten by any known insect. A removable washable cover should be used with your duvet at all times.
