The human body needs to breathe whether it is nose, mouth or skin. Many sweat pores on the surface of your body are sweating all the time. If you wrap it in a piece of plastic, you don't need a night, even if you can't stand it for half an hour, you will be sweating all over. Have you ever tried wearing a raincoat in summer? What's more, sleeping is a state of people and needs a comfortable environment.

Even quilts are gradually replaced by silkworm babies and health quilts. Silk is a kind of protein, and its chemical composition is similar to human skin. Silk itself is very slender, with good air permeability, hygiene, environmental protection and comfort, far exceeding the quilt.

Some people think that silk is light and soft and won't keep warm? That's a misunderstanding. Silk has a low density. Among all kinds of textile materials, the volume per unit weight is the largest, so it contains the most stagnant air and is the warmest! Generally, 4 kg silk is warmer than 6 kg quilt, and the comfort is incomparable to the quilt. Do you think it's easier to weigh 4 kg or 6 kg on your body?
