The sleeping bag is really thin and accordingly unsuitable for the input temperature. Temperature limit already at 14 ° and Comfort at 18-20 ° C.
A test in the tent (TiPi), pointing to a cot that I even 10 ° C and fully dressed even a thick jumper needed at night at +. Subtracting warm it no longer fits into the sleeping bag. :)
So definitely only for those warm summer nights to recommend the sleeping bag.
