I loved the size of the bag, color, compartments. It fit all my pumping gear. I’m so sad that it was just stolen today. I’ve only had it for two weeks. I decided to purchase another Sarah wells bag because the only issue with this bag was it got really heavy on my shoulders. I ended up purchasing a the Norah backpack.


I love this so much! I use it for a pumping/diaper bag. It’s has so much room for all the things! They really thought of everything when they designed this bag! My favorite part is that you can fit the color bag in one of the outside compartments! I highly recommend this bag to anyone even if your not pumping!

I got the Lizzy bag with the Ceres Chill for my work and school life. Having this incredible bag made me shocked at how easy getting ready to head out the door with my lil coffee bean was!! All the pockets are awesome, even then the side pocket are full, I still have a good amount of space to put more things in the bag. I absolutely love the design and it looks even better in person. It softens the blow of having to part ways in the morning with my baby! Knowing I am prepared with a durable, well thought out bag to keep my milk supply in order for my baby is a really awesome feeling. So grateful for this bag with my transition back to work and school!!

Love this bag

I just returned to work and this bag has made life so much easier. I don’t have an office and need to pump in communal areas- having my pump (I’m using the willow) easily accessible in this bag has been key. The insulated pocket for milk storage is genius. I can’t recommend it enough to pumping mamas.
