The insulated compartment can be detached if you want to convert the bag into a lunch bag, trip or camping bag, wine carrier and more. For that reason, you can use the bag for other purposes if you’re no longer pumping.

We like how it is constructed to be tall to suit tall milk bottles then close nicely without an issue. You’ll love how the bag unzips widely to help you fit and remove the tall bottles.

Since this is a multipurpose bag, it is huge with front and side pockets to fit all your baby’s breastfeeding products for use on the go. The best part is how you can wear as a crossbody bag when you have other items to carry with you to the daycare.

We like the big capacity that comprise of big compartments and a bunch of smaller pockets to fit all your baby’s breastfeeding and diapering essentials.

One outstanding feature is the zippered design that opens wide to help you access the base or pack the breast pump and baby bottles a lot easier.

But the favorite feature amongst the moms is the lightweight and portable design without feeling heavy; and the adjustable strap that’s easy to alter to suit the shoulder’s needs.

  • Opens wide to access the bottom
  • Adjustable shoulder straps


  • We wish the bottom of bag would detach

Another notable feature is the solid fabric material that will last all through your bottle-feeding journey. The only downside about this bag when compared to others we’ve reviewed is that this one is a little compact so it may not accommodate a lot of baby essentials or tall bottles.

How to Choose the Best Cooler for Frozen Breast Milk

Ways of Cooling

There are three ways to preserve the milk depending on how the cooler bag is constructed. The most popular method is the use of ice pack. Here, an ice pack is inserted to keep the milk cold, fresh and safe in the outdoor trips.

The next method is the use of gel lined coolers. You’re supposed to refrigerate the gel overnight ahead of use. For that reason, they’re not that convenient for random trips.

A rare but efficient choice is the use of portable refrigerator bag. The method will need you to connect the bag to a power source or car battery to maintain the milk at cold temperatures.


The best cooler bag is divided into at least two large compartments: the upper and bottom parts; and a back & front pocket. There are a few models with other extra pockets to meet your storage needs.

Additional pockets are essential to store your snacks and other baby accessories so there will be no need for an extra lunch bag. We suggest you pick a cooler bag that fits short bottles as well as tall baby bottles of 9oz.

Waterproof Lining

The purpose of the lining is to shield the rest of the stuff in the event of mess or leakage. A waterproof bag is easy to wipe since the wetness will not penetrate into neighboring compartments.


When shopping for a cooler bag, check the design of the shoulder straps to see if you can wear as crossbody bag. The reason for this is because you probably have to carry some other things with you as you head to the daycare.


A versatile cooler bag can be transformed into a regular bag if you’re no longer pumping. You should be able to detach the divider and use the bag for ordinally purposes.


With the myriad of cooler bags available, there’s no need to worry if you want to go out on a road trip with your little wonder. There are tons of cute and stylish coolers for breastmilk that will match with your outfit.  

The best cooler for frozen breast milk will ensure the milk is fresh without compromising with the nutrients therein. At the colder temperatures, the milk can stay for as long as 24-hours.
