White goose down is the best filling material for beddings, because it traps the body heat, and helps to insulate against heat loss. That makes these products the best beddings for cold winters. The down is the perfect choice for warmer seasons too, because it lets moisture evacuate to avoid feeling hot. Down is softer than feather, allowing a very gentle cover around your body. Goose offers the best quality natural fillings. Goose down and feather fillings offer excellent and luxurious quality and it is extremely durable too. Feather is more suitable for pillows, because it perfectly supports the head and neck. During the filling process the manufacturers combine feather with some down (the ratio depends on the customers’ needs) to give the bedding products extra softness. Duck filling make the bedding products less warm.
