Returned this bag as damaged but rebought product elsewhere and v disappointed. Only just fits two avent natural bottles but you have to force them in and the inside of bag has ripped completely. Rubbish product.
I'm very surprised that this bag is still in sale. Does not keep bottle warm at all. I have impression that bottles stays warm longer if i just put it in my handbag than if i use avent bag that is cold from the begging. Waste of money.
