What’s the different with Pacific Coast’s baffle box and other comforter?

This comforter’s design and construction is not sewn through, but has a vertical wall of fabric, baffle, joining the upper and lower portions of the shell. Baffles allow the down fill to reach it’s maximum loft and prevent the down from shifting and creating cold spots. Down comforters designed using a baffle are typically much more expensive to manufacture than a sewn-thru box construction.
