I have been looking for a polyester based duvet cover because when washed and dried, they do not wrinkle. In addition, they are light in weight. I change my duvet cover weekly and I wanted a product that would not fade after several washings or wrinkle. This is an excellent product. I have purchased them in bulk which reduces the price and plan to give them as gifts. I have spent a great deal more for duvet covers which I have thrown away before a year. I feel comfortable recommending these as an excellent product. A side benefit which I did not anticipate is that my cat's fur does not seem to adhere to it as much as my other duvet covers.
