The soft, elastic and cuddly duvet is very nice airy in the warmer months, overheating is avoided. These days you do not even know what one of the youngest (my 9 weeks old) can attract at night, so they do not overheat. A sleeping bag is definitely not, with these blanket and underarm body is doing very well. Even on the go in the stroller or car seat blanket is prima suitable. And you can spit so also very good. The ceiling is wonderfully soft and cuddly, and I wash without fabric softener - the verdict of the previous review I can not understand therefore.
