Great warm sleeping bag. We had enough of the on and off the pajamas (for example at night when wind). This sleeping bag you do not need pajamas (had only one Langarmbody on). He also holds not warm, but overheated. Our son will not have sweat and not frozen. Which is precisely correct. (We have 17 degrees in the bedroom.) The zipper is protected up so that the chin does not rub it. The child can not slip even purely because the hole just the right size. Great value.
