Important note,please read before you purchase Some buyers feedback that this pants do not like really natural silk.We would like to make an explanation below: The most common silk fabric is plain silk or chameuse silk,smooth on one side with luster and coarse & dull on other side, which is also called silk satin,widely used to make silk sleepwear,underwear, silk sheets set. Some buyers only know silk satin, they take this as the only natural silk products. In fact, natural silk fiber can be made in various different style fabric,like Damask,Gauze,Georgette and so on. Not all natural silk fabric is smooth and has luster. For this silk cashmere pants,it is not like the common silk satin * The silk fiber is spun silk, which is the inner layer silk fiber in silk cocoon. It may be mix-up with cocoon shell impurities. The luster and breathable property is inferior compared to outer layer silk fiber. So the spun silk is commonly used to make silk blend sweater, pants,silk gloves and silk socks. * The woven method for this pants is Full Needle Knit Method, so the fabric is quite thick and tight with high density stitches to ensure the pants are warm and durable enough.But the tightly knitted fabric will be a bit stiff, sometime it need be sand-washed to make it softer.
