Our True North All Season warmth down blend comforter takes a very unique approach to keeping you toasty warm on those cold winter nights. Most down blend comforters are just that, a blend of down and feather throughout the entire comforter. Our comforter features a proprietary construction which puts only high quality 550 Fill Power white down in nearly two- thirds of the comforter (the part you sleep under) and fills the side panels (the part that hangs over the edge of your bed) with a blend of 80% feather and 20% down. With a little over 55% of a comforter resting on top of your mattress and the remainder falling over the edges, we're giving you more down where you need it. The end result is you're sleeping underneath a high quality white down comforter for the price of a down blend comforter. Our oversized comforter is constructed with a 233 thread count, 100% cotton down proof percale cover throughout and the white down filled section features 'end to end' sewn though box quilting to ensure that you'll never have any cold spots due to the down shifting around.
