This luxuriously soft comforter from Pacific Coast is perfect for use in all seasons. It's constructed from the finest materials to ensure your comfortable sleep for many years to come. The comforter features an outer shell of 260-thread-count Barrier Weave cotton. The fibers are woven extra tightly to produce a smooth, leak-proof fabric. Inside, there's a substantial amount of 525-fill-power down. This down has been selected, sorted, and cleaned by hand to remove dust, dirt, and allergens. Called HyperClean, this cleaning process not only produces down that is cleaner than that used in other products, it's also fluffier and longer lasting. To ensure that the down stays on top of you while you sleep, this comforter has a Comfort Lock border and a 15-inch diamond box design. Pacific Coast provides a 30-night comfort guarantee and a five-year limited warranty for this comforter. PACIFIC COAST FEATHER ESSENTIAL YEAR-ROUND WARMTH TWIN DOWN COMFORTER
