The Moomee "Washed Cotton Linen Like" collection gives your bedding a rich look, while pure cotton offers a unique blend of comfort, practicality and elegance. Woven from the world’s finest Long-staple cotton, the naturally soft cotton is water washed to enhance its feel and relaxed look. Cool in the summer and insulating in the winter, it offers breathable comfort all along. The duvet cover is designed as a removable cover for your duvet/comforter (sometimes even for your quilt). It can be removed and laundered as often as the bottom sheet and pillow cases. This keeps the duvet fresh as well. Duvet covers from MooMee feature zip closure and four interior corner ties to keep the cover secure.
