"Designed to support a more comfortable night’s sleep, the Slumberdown Climate Control Duvet uses breathable Dacron® fibres to help regulate body temperature as you rest. Moisture is drawn away from the body while air circulation is improved, creating a drier, cooler feel that suits those who tend to overheat during the night. With a soft-touch microfibre cover and a non-allergenic filling, this duvet is a considered choice for everyday bedrooms and for allergy sufferers seeking a fresher, more hygienic sleep environment. Choose from 4.5, 10.5 or 13.5 tog to match the season and your preferred warmth, with sizes available from Single through to Super King.
