Down is the light fluffy coating found beneath the feathers of geese and ducks. Down is a three-dimensional cluster with dozens of soft, fine filaments that radiate from its centre. Down comes with a variety of features. It keeps you both warm and cool. Down is a breathable material. Because of its high fill power, less down is required to fill up the pillows and duvets. Therefore, there is a lot of room within the down clusters for the air to circulate. It offers all of these features without ever compromising on the comfort factor. Feathers do not come with any of these advantages.
