Great quality perfect for on the go!
AMAZING. I bought this before my first ever flying trip while nursing. It is great quality, fits my pump well and hold quite a bit of milk (I used bags instead of bottles) it was easy for security to search and small and portable to carry on the plane and in the car with me on our trip. Highly recommend.

Good quality bag
Love this! Bought this because I got the Zomee Fit, hands free wearable pump and wanted a bag that would hold them along with supplies. This is about the size of a lunch bag so it takes up some space, but not a lot. It’s like a midsize purse so it’s easy to pack and go. Quality of the zippers is good, I’ve used quite a few times and they have not given out or gotten stuck. The material of the bag is pretty durable and good quality. I haven’t had any stretching issues, or tears. The bag is designed to hold the pumps on one side and the bottles on the other. It comes with an ice pack thing that you actually have to add water to on the first time use in order to freeze. I didn’t use the ice pack because I breastfeed and just needed this bag for storage of my pumps, milk bags, nipple ointment, and bra pads. This bag design helps me carry everything I need. I would definitely buy this again for any future kids.

Cute breastmilk travel cooler
Lots of spaace for 6 bottles, two pockets one cooler inside with ice pack included, the other for Travel pump parts and pieces. I can fit my elvie pump in there and bags with room. Two water bottle holders on the sides and extra smaller pockets on the outside. Keeps my milk cold at work and on the go. I just wipe down to clean very easy to do, seems like I could just throw it in the washer as well but I haven’t yet. A+for functionality, design and durability. I’ve been using for 6 months so far and will continue until I can’t.

Great for working moms needing to pump. Discreet and spacious
Perfect for going back to work and breastfeeding! Plenty of room for my wearable pumps or hand pumps and super discreet. Love the included ice pack to keep my pumped milk cold.

Essential for Pumping Moms – Just One Small Fit Issue
I use this breastmilk bottle and pump holder every single day, and it’s been such a lifesaver for storing milk on the go. The insulated design and included ice pack keep everything cold for hours, which gives me peace of mind whether I’m at work or out running errands. It fits several bottles and my pump parts nicely, and the compact size makes it easy to carry or toss in a diaper bag. The quality feels great, and the ice pack holds temperature really well. My only small complaint is that when all the bottles are full, it becomes a very snug fit—zipping it up over the ice pack can take some careful arranging. Not a dealbreaker at all, but something to be aware of if you regularly carry multiple full bottles. Still, this cooler bag is one of my most-used baby items. Highly recommend for pumping moms!

It’s a must have !
I still use it everyday because I was carrying around my pumps in a plastic bag , I keep it with my diaper bag and it’s so cute and really good quality : the ice pack works so well . Keeps the milk cold for hours so I don’t worry about it going bad meanwhile I get back home . It fits a lot , I even stick a diaper and some wipes in there when it’s just a quick run out somewhere

On the go pumping made easy!
This has been great for on the go pumping. Fits my Momcozy M6 pump, two bottles for storage, an ice pack, plus chargers or chapsticks on the outside. Roomy and handy!

The best bag ever for breastfeeding moms on the go. I take this bag everywhere when I leave the house for a long time. I took it to Florida and it was so handy on the plane and airport! it fits my Momcozy M5 pumps and my Medela hand pump. the cooler section fits 3 medela bottles perfectly to keep them cool for up to 24 hours (I've tested it)

This is the best diaper bag. Compact for quick adventures with baby. Fits my m5 perfectly with bottles, diapers wipes, extra cloths and even my portable bottle warmer. The other diaper bags a big and bulky. This is a keeper.

A lot smaller than I thought it would be. Very similar to a lunch bag. Super snug fit and won’t fit both the freezer pack and AVENT anti colic bottles or any other wide bottles at the same time. The material and product works as intended just wish the bag was bigger.

The icepack was missing, the pockets space was small and the quality of the zippers was not great.

Very disappointed. I use the skinniest 4oz Dr. Browns bottles, and I don’t know how you would fit a wider one. Could not fit comfortable my medela hands free pump cups and pump. Could barely do the zipper up. On the bottle side you can definitely only fit 3 skinny bottles and even at that it’s super tight.
