The ceres chill bottle! 10/10 recommend!
I have this one and it’s great. There’s a section that holds the pump at the top and below is the cooler bag section that comes with an ice pack and holds 6 milk storage bottles. Or you can remove the separation in the middle if you only want to use it as a cooler bag. Can be used after pumping journey as a regular cooler bag too. https://a.co/d/4ZeO0zj
I use this one: https://a.co/d/0mLXaqp I love it. I have large ice packs that I use. I've been able to fit 6 Lansinoh bottles and an extra bag of milk with ice packs in the bottom and use the top for carrying the bottle warmer. It has the added bonus of removing the middle barrier and can use it for a wine carrier when done with bottles 🤣.
We just have a bunch of random cooler bags. I just grab whatever I have. Sometimes I take a small one and sometimes I take a medium size one.
