Diaper Bag Suggestions- I Hate My Current Bag!

I’m looking for diaper bag recommendations. We currently have a generic Amazon backpack style. It’s ridiculously bulky and heavy! We’re expecting baby #2 and I am not dealing with our bag anymore!

I am almost tempted to get something like a jansport backpack. I want something lightweight and flexible like that. However, we will occasionally need an insulated section for bottles/pumped milk.

Any suggestions? I also don’t care about name brands and don’t want to spend an outrageous amount of money.
