Perfect for camping couple, holding warm even by night a little cool (7-10 °), not below, it is not for an expedition to the north pole either. Storage side, it rolls into a bag without torture session to force to go, it quietly goes without forcing. The interior bag is known canvas type cotton, very pleasant, without the plastic side of the said bags "technical". it unzips completely, so it can move on to the machine 2 times. A very good choice and purchase.
