halvdun

Halvdun is a Swedish term used to describe a specific type of down filling. It literally translates to "half down" and refers to a mixture of down and feathers. The ratio of down to feathers in halvdun can vary, but it generally contains a higher proportion of feathers than pure down. This composition impacts the properties of the filling. While pure down is exceptionally light, lofty, and insulating, halvdun offers a good balance of warmth and compressibility. The feathers contribute to the overall structure and loft of the filling, preventing it from clumping as easily as pure down might. However, it is typically less insulating and lighter than 100% down for the same volume. Halvdun is often used in products where a balance of warmth, durability, and cost-effectiveness is desired, such as duvets, pillows, and outerwear. It provides a comfortable and warm filling that is more affordable than pure down. The presence of feathers also adds a slight stiffness to the material.
