Experience ultimate comfort with climate control with this Slumberdown Climate Control 10.5Tog Single Bed Duvet. It's crafted to control your temperature so you never experience too much heat or cold while sleeping. The Dacron hollow fibre fill keeps the duvet surface and body at a consistent temperature. The filling works harder to keep you cool as you produce more heat but it also keeps you from becoming too cold when you're already cool. It is ideal for year-round use because of its mid-weight 10.5Tog construction. You may rest easy knowing that no allergens with their hypoallergenic qualities will keep you up at night.
