10 Best Flannel Duvets 2026 in the United States

Weighing about 6.5 pounds, it feels cozy without being overly heavy. The King/Cal King size is ideal for larger beds, and the white solid color with a modern style will easily fit many bedroom decors. Care is straightforward with machine washing in cold water and tumble drying on medium heat, though natural shrinkage should be expected.
