Bought early summer, however, I would like now to say that I am completely satisfied with the sleeping bag. Bought - originally a very spontaneous action is an even more spontaneous holidays - keeps the bag what it promises, despite very warm and humid air in the tent of the bag holds not warmer than I consider to be pleasant. Even I slip not so on a camping mat, reported as other reviewers. The substance is at night when moving not necessarily low, which could interfere with one or the other, but for me no shortcoming, it is more important to me that it is easy to carry. What me is also important is that the sleeping bag is easy to pack back into the original package, and that works with this even if I just shove him in.
All in all, for 35 a genius sleeping bag that will accompany micht hopefully more often into the tent.
Update:
Now that I have tested the sleeping bag thoroughly, inside and outside in the tent, I do not want to part with it myself. Even if you take sleeping right next to a radiator, it is in a sleeping bag is not warmer than pleasant. Fully opened, you can use it as a blanket him even. Late August / early September, I slept for two weeks is strictly in this sleeping bag in feutchkaltem air. A dream, throughout toasty warm in the sleeping bag, the humidity is not noticed in the sleeping bag. Furthermore, full 5 stars from me, I would buy this sleeping bag immediately.
