The silk sleeping bag is considerably less expensive than the major brands. The color is gorgeous. A natural burgundy. Not as beige as the usual models. If at some point no longer go wandering, you can sew so least something fancy from the beautiful fabric. The silk is very pleasant on the skin. At the cottage with horse blanket over it pleasantly warm and very cozy. I use the silk sleeping bag even in hotels that do not appear very clean to me. Only the Kletti is stupid. Also goes on frequently. I'll replace him once by a ribbon tie. The large entry I also need not necessarily. You could also sew. But all have. On the whole, I am very satisfied with the sleeping bag. The silk part is also super easy. That's why I've decided for silk instead of cotton. Cotton weighs twice to three times as much and dries poorly. Synthetic fibers (polyester microfiber), I did not. Indicated are approximately 140 g. I have re-weighed. With shell about 136 g - without cover, so the ticking alone, around 130 g Perfect..
