Fully half-baked product. Packing size about 3 times as large as the presentation suggested. Inferior, heavy materials that do not heat. So really everything a sleeping bag should not be. -If You are looking for a sleeping bag that warms a bit, there are plenty of models that wonderful fulfill this purpose in this weight and pack size. But not this one. -If You are really looking for a sleeping bag as a sleeping bag or sleeping bag liner, there are plenty of models that have about one-tenth the weight and Packmases. I can almost not believe who and why has designed this part here.
