Silk sleepwear will protect your skin
On that note, silk pajamas are the best pajamas for your skin. Cotton and synthetic fabrics are known to stress out your skin. They scratch the surface of the skin, trap heat, and draw out moisture. Silk pajamas, however, are soothing to the skin. They help the skin retain its moisture through the night, prevent wrinkles, and protect the skin from scratchy cotton bedding.
What is momme?
Momme is the fabric weight of silk fabrics (it's used instead of thread count). In general, the higher the momme, the better the quality of the silk.
