Silk is an amazing material that regulates temperature better than any other fabric. It acts warmer in winter and cooler in summer. Unlike cotton, which is a plant material, silk is a protein from the coccoon of the silk moth. Silk contains 18 amino acids which are similar to those in another protein, the human skin, and, as the Chinese have known for centuries, silk rejuvenates the skin. By wearing silk nightwear you can improve the health and appearance of your skin, and you can enjoy its soft, soothing feel. Pamper yourself with our exquisite Kookoon silk nightwear. These also make great gifts!
