Our silk sheets are made with the finest quality 19 Momme weight mulberry silk. Silk is often valued not only for its ability to bring about comfortable sleep, but also for its health benefits. Unlike cotton, silk doesn't absorb moisture from the skin and hair, contributing to soft skin with reduced wrinkles as well as glossy healthy hair. Silk is also naturally hypoallergenic and adjusted to your body temperature. In addition, LovaSilk is produced without the use of bleach or other harmful chemicals, for a natural, comfortable and safe sleep.
