    Worked Great
    This was used for cross country travel to store milk when I pumped and to feed baby. It worked/works great. We love the top compartment for storing snacks, milk bags or anything else we might want. It is decently sized and holds several reusable ice packs and milk. The ice pack that comes with it is great for bottles. I even used it to keep icecream cold on the way home. It kept the milk cold for our hours long journey and really was a great buy. It’s well made and does what it needs to do

    Quality-Two Compartment-Zippered Bag
    This bag is quite nice. I purchase this bag to assist with my infant/toddlers bottled milk. It will hold 6 Dr Browns bottles or other brand with iincluded ice pack at the zippered bottom. The zippered top holds homemade containers of baby food or store brought jars of food etc. The color “black” is great choice for moms, dads, grandparent’s who prefer neutral color that will go with any outfit. It has a very long. shoulder strap, especially works well with 5”8-6 foot tall people. Its also has a smaller, adjustable strap as well-to carry in hand instead of cross shoulder strap. The fabric is waterproof interior and exterior-will not leak. I especially like the two different zippered compartments that may Benifit warm food while the bottom remains cold.**I highly recommend this bag to all…whether nursing mom or working mom, dad, grandparent who wants a nice black casual bag to carry essentials**

    I LOVE THIS COOLER BAG!!
    I’m obsessed with this cooler bag! It has so much room and is super cute! It keeps my breastmilk cold ALL day! You can even keep your drinks in it. It has room left over on top even with my 9 oz bottles! It fits my Dr brown wide neck bottles, Phillips avent natural response, tommee tippee, Medela and many more bottles! I love that I can keep my momcozy pump up top and still have room for snacks if I wanted. After I pump I keep my momcozy in the cooler part to keep it cold and fresh for my next pump if I don’t have anywhere to wash them. And I absolutely love the pocket on the back that I keep my phone in. It’s perfect!! I’m super happy with my purchase and recommend this bag to everyone! GET IT!!

    Great Cooler
    This is a great cooler for pumping, storing milk, and packing lunches. The cooler is a good size and it can fit all of the pumping parts and bottles. I still use the cooler as a lunch box!

    Functional and practical
    Very functional! Much easier than fitting all the food items for my baby while he’s in daycare in his diaper bag.

    Great for a family on the go!
    We are always one go and have stuff to do and with this we do not have to worry about having to be home to feed our baby. I holds all of the bottles we need and the top storage it actually pretty big we can fit the bottle warmer in it. Just be careful to make sure it stays up right so the bottles do not spill, learn from our experience! Great product!

    Cute and Spacious, and Not so Obvious
    Love this bag and I get compliments about it all the time. People often confuse it with a lunch bag and i appreciate the discretion it provides. I don’t always want to be a walking billboard just because I’m breastfeeding.

    I use this every single time I leave the house. It’s perfect to fit everything I need for my baby. The size is functional. I am able to fit all his snacks, multiple meals and a 1L milk bottle plus his drinking bottles. It keeps the temperature of the food & milk well.

    I bought this thinking we would use it much as we don’t go out with the little one all that often. However, he started daycare at 11 months and was still on milk in bottles. This bag came in so handy for packing his bottles, so others and medication if needed to take to the daycare each morning.

    Awesome little bag. Exactly as described. Has helped a few times already when we or I alone had to leave with my son. Bottom carried his bottles and our drinks as well as a few snacks and the top fit my breast pumps so I could pump while we were out and they stayed cold. Does come with a bottle ice pack for the bottom so you should also get purchase a small one for the top.
