They are ideal for bedrooms under 20 degrees, though they can be used in rooms 14 to 22 degrees by varying the clothing inside the bag. Ideal for for cooler homes and the colder months of the year. The Duvet Woolbabe has the heavier feel of a quilt or layers of wool blankets, with the peace of mind that comes with your baby sleeping in a sleeping bag designed with safety as a priority.
