This percale duvet cover, white with an ivory border and embroidered piping to provide a subtle contrast, is made of luxurious Egyptian cotton, a long-lasting fiber that will become even softer over time. It will also resist the pilling found with lesser fabrics. Six decades ago, in a small town in the Italian province of Bergamo, Zambaiti began producing blankets and throws. It has since become world-renowned for its sophisticated bedding, which now includes linens of luxurious Egyptian cotton with distinctively high thread counts.
