Mari Ann silk bedding is made with the finest 19 momme mulberry silk, which is made under controlled conditions. The result is a fiber that is considered the strongest in the world and thus a more durable weave. Mari Ann only utilizes the top 3% of mulberry silk to fill their lightest and most breathable all season comforters. Besides being extremely soft and comfortable, sleeping on silk pillowcases has some other benefits. Did you know that sleeping on smooth silk instead of cotton causes less friction to the hair so you’ll have less broken hairs or that funny bed-head look when you wake up? And, silk actually helps retain skin moisture which means less wrinkles and fine lines. No wonder its been around for over 5,000 years!
