The Bags I Tested
The [Skip Hop Forma Diaper Backpack with Bottle Sleeves](https://www.amazon.com/s?k=Skip+Hop+Forma+Diaper+Backpack+with+Bottle+Sleeves&tag=thetestedhub-20) was my daily driver. Two insulated side sleeves held bottles upright and warm.
Questions answered
About two to three hours in the bags I compared. Cold drinks lasted longer, around four to five hours before warming significantly.
Most fit wide neck bottles like Dr Browns or Comotomo. Two of the five had narrow sleeves that struggled with the wider bottles.
