Our certified Pima cotton is extra-long staple cotton, known for its long, smooth fibers. It is woven into a high quality fabric that is soft and durable. 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. Available in a wide range of colours, it’s designed to suit any style or space. 400 thread count 100% combed cotton sateen, certified Pima Cotton Knife edge seamed cover with 60" side zipper for easy removal Oversized to account for shrinkage Housewife fold on pillowcases prevent pillow slippage and help to dress the bed 4 corner tie down matched with our duvets with loops to keep everything in place.
