It is extremely comfortable and you stay nice and warm all over. In my pregnancy the jumpsuit has then served me well. Even in the 40th week of pregnancy the belly fits well into the suit. ^^
Disadvantage of a jumpsuit in general is of course, the one a one piece, of course, completely takes off when you have to go to the toilet once.
For size: I ordered the suit in M / L. In fact, one bears man usually XL.
