Egyptian cotton is a long staple cotton grown in the ideal conditions that exist in Egypt. This cotton, known for its long, smooth fibers is woven into a high quality fabric that is smooth, soft and durable. Made with 100% Egyptian Cotton with a thread count of 400 per square inch, we have also created a sheet that is breathable. The threads are not overly compacted, as with extra high thread count sheets, thereby allowing the air to flow through the sheet and keep you cool. These sateen sheets feel silky and smooth.
