Preis-Leistung TOP!
Quality: mediocre, I would say, but absolutely to the price okay.
ADDENDUM:
The sleeping bag was used for camping from me and my girlfriend at the last holiday in Denmark.
We have absolutely no complaints, at outdoor temperatures of wet 6 ° C at night in 100m distance to the sea we both never frozen and my girlfriend is a frostbite)
The zipper stuck here and there and a bit tricky to thread again in the dark when one is in it, but also that you get with a little patience in the handle. My advice: just do not let the zipper down the stop but pull slightly upwards, so the carriage can not easily hoppsen from the lead in clean creep.
My conclusion remains the same: price-performance super.
