The cotton has been given a gentle softwash that gives a beautiful matte finish. It feels soft against the skin and is nice cool but 'crisp' to the touch like a cotton percale is. The 310 thread count long cotton fibers will only become softer and nicer to sleep in over time and in a quality that makes this product something you want to keep for many years. The fabric is produced in Portugal in a recognized factory that has spun and produced bedding since the 18th century. Both duvet covers and pillowcases are closed with a hidden zipper.
