Like three bedcovers in one, this is the down comforter with detachable layers that can be used individually or in combination to keep you comfortably warm as the seasons change. Filled with hypoallergenic 100% white duck down throughout, the lighter weight layer (10-12 oz.) is for use in Summer, the heavier layer (25-30 oz.) is for use in Spring and Fall, and both layers can be snapped together to ward off chills on frigid Winter nights. Sixteen snaps around the perimeter secure the layers. Each 450 fill power layer is covered in 300 thread-count 100% cotton sateen using a stitched baffle-box design that keeps the fill from shifting and bunching, ensuring an even surface without hot or cold spots. Machine wash. White. Queen. 90" L x 90" W. (2 1/2 lbs.)
