What is a "down comforter"?

A down comforter is a thick, soft blanket filled with the fluffy feathers from ducks or geese, known as down. The down filling provides excellent warmth while remaining lightweight and breathable. Down comforters are often used in colder weather, as they are designed to trap body heat and keep the sleeper warm without feeling heavy. The outer cover is typically made of cotton or a soft fabric to add comfort. Down comforters come in various sizes and can be found in different warmth levels to suit different climates or personal preferences.
