cover with opening on the sides

[Jostudly]

Hi I just bought a new hot tub and noticed the cover has openings on the sides in the middle. There are leather flaps that are there but can still see an opening. Just wondering if all covers are made this way? Not sure if this is for ventilation but I am wondering if this will bring in cold air in the winter and make the heater work harder.
