This sleeping bag I can put each only to the heart. He keeps very warm to temperatures around zero degrees. I use it to here and there anywhere to sleep on a couch at room temperature around 20 degrees. If you leave the zipper open, then it is not too warm. It's also nice to use it just so watching TV, instead of curling up in a blanket. Couple sleeping bag is definitely too tight. The zipper is then no longer gets to. I sleep every weekend in him and I can highly recommend it. The quality of cotton and polyester, as well as the seams and Reißverschlussese are without flaws. A secret compartment located inside.
The heat and moisture circulation functioned perfectly. I often sweat a lot while sleeping, but this sleeping bag was the morning always dry.
Before first use, I recommend the sleeping bag once neat to use the washing machine. The fragrance lasts a very long time in the sleeping bag.
