Restoration Hardware queen sized duvet. Graphite (looks like a slate blue). Luxurious, beautiful and sustainable, our organic linen bedding is exquisitely loomed from the finest Belgian flax. Harvested with care, the flax is smoothly spun and yarn dyed in understated hues. The fine yarns lend the mid-weight bedding a relaxed drape and effortless elegance, along with a natural softness that's enhanced by a special stone wash. Meant to enjoy for years to come, the heirloom-quality linen only becomes more supple over time.
