The comforter is filled with white duck down. Duck down is known for its softness, lightweight feel, and excellent insulating properties. It has a 300 thread count. The comforter is RDS (Responsible Down Standard) certified. This certification ensures that the down used in the comforter comes from ethically and responsibly sourced ducks. RDS certification guarantees that the ducks were treated humanely and that the down production adheres to strict animal welfare standards. The comforter has a fill power of 550. Fill power refers to the volume of space that one ounce of down occupies. A fill power of 550 indicates high-quality down with good loft, insulation, and fluffiness. The comforter features a baffle box design. Baffle box construction includes fabric walls between the top and bottom layers of the comforter, creating individual compartments or boxes. This design prevents the down from shifting or clumping in one area, ensuring even distribution of warmth and maintaining the overall loft of the comforter. The comforter is available in two sizes: queen (90x90 inches) and king (106x90 inches). The queen size has a fill weight of approximately 34.5 ounces, while the king size has a fill weight of approximately 42 ounces.
