The sleeping bag is really super small and can be due to the compression straps without problems back to pack up to the delivery size. What I really liked is that you also can aufzippen him at the foot and thus can make a real blanket of it. I had him here on a road trip and found this function, for example, for long bus rides beautifully. But you should already be aware that it is dealing here with a sleeping bag, under 12-15 degrees room temperature, it is quite uncomfortable.
