Product review (5 stars): awesome bag
Love this bag!
I had to pack it the afternoon before I was going to use it and everything was still cool the next morning.
We had something leak inside the bag and none of it came through the bag.
 I put around 15 juice boxes, 10 small powerades a gallon size ziplock bag packed tight with snacks and a couple of plastic containers along with a good sized ice pack.
I was also able to fit a couple of child harnesses, diapers, 3 small battery operated fans, wallet and probably a few other things in the outside pocket and was still able to snap it.
Packed full the way I had it, it barely fit into the bottom basket of our double  stroller. It was also heavy enough that it made the stroller basket come open a few times. It's really cute. You would never think it was a cooler.
