For a summer sleeping bag at such a price-excellent quality. Pleasant color, smooth seams, branded accessories. It is clear that the seams are through and the zipper is not full-weight! (626g with case) With active shaking, the fluff does not climb, after compression it is well straightened. With an increase of 183 cm and a mass of 105 kg, I fit comfortably. Miracles of survival at okolonulevy temperatures from it I do not expect.)) But, from May to September, I think, will serve well. Five stars.
