The best quality duvet covers are frequently made from advanced fabrics such as poly-fiber, which is composed of extremely fine, synthetic fibers and often used to produce high-tech exercise clothing. Because of the short strands, this material is excellent for night sweats because it allows moisture to escape rather than be absorbed by the body. The poly-fiber that is used in duvet covers is often brushed to give it a softer texture. Home City Inc.’s duvet covers have been finished with a brushed finish, which results in an ultra-soft 1500 threads per square inch. They are also more robust and stain and fade resistant than cotton, making them an excellent choice for daily use. Furthermore, because they are made of inorganic materials, duvet covers are hypoallergenic and can help to reduce the frequency of allergy attacks.

'Satin is great for sensitive skin and allergy sufferers however it is harder to clean and more expensive than most sheets,' says Bed Bath & Beyond.
